Welding aluminium is pretty popular in the manufacturing and aerospace industries many thanks to its special mechanical houses. Aluminium is light-weight, durable and rather resistant to corrosion, creating it an interesting alternative for some purposes in contrast to other metals.
Aluminium welding faces a set of special issues nevertheless, to accomplish a effective and defect-totally free final result.
The Issues in Welding Aluminium
Welding aluminium is a intricate method that calls for expertise, ability, and expertise. Comprehension the various welding procedures appropriate for aluminium and the challenges and workarounds relating to people techniques is paramount for obtaining profitable welding joints.
Oxidation
Aluminium promptly oxidises when uncovered to the ambiance, forming a slender oxide layer with a bigger melting temperature (2072 C°) than aluminium (660 C°). Welding by this barrier may well burn up holes through the workpiece.
The oxide layer can be dissolved utilizing solvents or acids right before welding the workpiece. It can be physically removed by way of mechanical abrasive tactics through an unique stainless steel wire brush or sandblasting.
Porousness
Aluminium in its molten state, absorbs substantial quantities of hydrogen, ensuing in very small voids or bubbles forming in the weld metal. This weakens the structural integrity of the metal, making it susceptible to failure from pressure and stress.
Porosity is minimised by applying clean up elements and tools, eliminating oil and grease from the metal’s floor, and employing a shielding gas to limit contamination.
Impurities
Oil, dirt, air and debris can negatively affect the weld zone, affecting the power and visual appearance of the workpiece. These impurities can arrive from several resources, this sort of as the ecosystem, tools, planning and storage. Discolouration, graining, corrosion and oxidation current indicators of impurities in a weld joint.
Correct storage, equipment maintenance and metal planning are the actions to get to avoid impurities.
Thickness
Performing with aluminium commonly consists of welding components with varying thicknesses. Welding through a mixture of slim and thick substance at the same time can be tough. Warmth used to the workpiece might soften as a result of the thin materials or not penetrate the thick content adequate to develop a solid weld joint.
A comprehensive comprehension of the aluminium grades, welding approaches, and techniques is the critical to achievements in efficiently welding different aluminium sheet thicknesses. Welders can properly weld these metals by placing the parameters such as amperage and heat input to best degrees.
Very hot Cracking
Significant ranges of thermal strain can direct to incredibly hot cracking or solidification cracking in aluminium welds. It is a single of the motives why aluminium was at the time deemed unsuitable for arc welding.
Combining various alloying components and treating aluminium alloys can considerably enhance its mechanical qualities. (Al-Cu) 2xxx and (Al-Zn) 7xxx quality series are aluminium alloys that can heat-taken care of.
Thermal Conductivity
The significant thermal conductivity of aluminium can make it tough to penetrate the weld joint successfully, as it absorbs and dissipates heat speedily.
Altering the configurations of the welding devices to larger heat input improves penetration.
Aluminium Welding Solutions
Numerous welding procedures are used for aluminium, each individual owning its possess strengths and weaknesses. Welders commonly opt for TIG and MIG welding, yet other solutions can fill in for a distinctive, attractive result.
Variables to take into consideration when picking the type of welding approach are the supply, price tag (products, filler materials, other consumables), weld overall performance, joint structure, repeatability, distortion tolerance, creation pace, and basic safety.
TIG Welding
Gasoline tungsten arc welding (GTAW) or TIG welding is just one of the most common welding techniques for signing up for aluminium due to the fact of its precision and top quality. It can operate on AC (alternating present-day) polarity, providing balance to the arc and wiping off the oxide layer. A TIG welder can persistently create ample warmth to fuse aluminium alloys, with the potential to weld both equally slender and thick sections.
Inert shielding gasoline, most normally argon, is fed to the TIG torch to hold the weld puddle cost-free from contamination. Therefore, shielding the delicate aluminium. When the challenge needs the use of aluminium filler rods, then collection 4xxx aluminium filler metal is the most common selection.
MIG Welding
Gasoline metal arc welding (GMAW) or MIG welding is a fantastic welding procedure for thicker aluminium sheets as the warmth input is higher than in TIG welding. This welding approach is fairly related to the TIG process but rather of a non-consumable tungsten electrode, MIG welding utilises an quickly fed electrode wire. The mechanical wire feeding process offers a lot quicker vacation speeds from its spool gun. Shielding gases are applied to defend the welds from contamination.
Laser Welding
Laser welding is a fast welding approach that concentrates a higher power density beam at the aluminium surface. It presents precision to weld both slender widths and big weld depths, ensuing in cleanse weld zones with the complement of shielding gas. 6xxx aluminium alloys are frequently protected for laser welding and are most typically paired with a 4032 or 4047 aluminium-quality filler rod.
Electron Beam Welding
Electron beam welding aluminium is an alternative for thick sections as it makes a small and precise weld pool. This welding process is carried out within a vacuum chamber, preserving the weld from impurities without the need to have for added shielding gases.
Resistance Welding
Resistance welding aluminium includes the application of force and current to undergo fusion. Location and seam welding is often applied to sign up for aluminium sheets. One particular draw back of this system is the attainable worries when going through large thermal and electrical conductivity.
Friction Welding
Friction welding is a stable-state fusion welding method wherein mechanical friction concerning aluminium metals generates heat. The nature of this procedure removes the requirement to insert a shielding agent to shield the weld pool. Friction welding is utilised across all aluminium alloy grades, which includes the challenging-to-weld 2xxx and 7xxx series.
What Procedures to Avoid When Welding Aluminium?
Processes that use flux (filler materials containing flux, granular flux, or other varieties) are not preferably ideal to weld aluminium as it faces a increased risk to porosity.
Aluminium Welding Best Methods
1. Safety and planning – Carrying protecting equipment (goggles, helmet, gloves, and many others.) is important as with any other welding process. Figuring out and comprehension how the job will be executed beforehand is a wonderful way to prepare for the welding course of action. Some preparation may perhaps consist of eradicating the metal’s oxide layer by way of chemical substances or a steel brush and making sure that the tools is clean up.
2. Comprehension the finer information – Knowledgeable welders convey much benefit in knowledge how matters need to pan out in executing a challenge. Finer aspects these kinds of as the welding processes, machines parameters and technique will assure a successful task. Finding your assemblies welded by seasoned welding company vendors will help to avert problems down the line.
3. Patience – It can take time to execute a stellar welding career properly, so it is critical to be affected individual and constantly check the parameters. Reproducible benefits with superior weld high quality are keys when welding several parts in succession.
4. Storage – Aluminium is stored indoors at place temperature and ought to be stored dry. It is greatest not to stack these metals if doable (ex. aluminium sheets), but instead vertically given that the metal is delicate.
5. Bead profile – A stringer bead profile is most popular in welding aluminium most of the time, compared with in welding steel, which takes advantage of a weaving technique.
A short while ago, Alpha Producing has seen a surge in demand for top quality Ireland sheet metal production, ensuing in the opening of two new divisions Alpha Built-in Systems and the most new remaining Alpha Producing Chemical Technologies, a 35,000sq ft purpose-developed production facility in Beacon Park, Stafford in partnership with world-wide chemical organization INEOS Electrochemical Alternatives.

Situation hardening is a metallurgical course of action that permits us to develop distinctive components with unique properties. In this short article, we investigate what it is, its method and its apps.
What Is Situation Hardening?
Situation hardening is a heat procedure procedure that hardens the area of a metal substrate when maintaining a softer main. This will allow to combine the most effective qualities of a tender and difficult metal into one portion.
A delicate substance can handle impact forces substantially greater than a tricky materials. It is also harder, a lot more ductile and stronger but it does not have enough don resistance. Superior use resistance is very important to ensure that the material does not have on away owing to abrasion or friction. By hardening just the outer surface, we can drastically cut down the carrying of product without having compromising other homes.
We can obtain the slender hardened surface by means of unique usually means these types of as altering the crystal structure and/or the addition of new aspects to the surface. But no make any difference the course of action, situation hardening almost constantly needs elevated temperatures.
When Is Case Hardening Made use of?
We use case hardening when we need to enhance the area hardness of softer components these kinds of as iron or small-carbon steel sections. The common follow is to do it just after all the machining and forming operations as it minimizes the machinability of a component. But we might also do it during previously levels of the production approach. Some of the instances where by case hardening procedure is applied are as follows:
Very low Funds
There is a considerable selling price difference amongst low-carbon steel and software steels this sort of as high-pace steel. The change can be much more than 20x in some instances. Thus, when the funds is a concern, we can use scenario-hardened small-carbon steel alternatively of device steel.
Also, circumstance hardening needs a lot less vitality and time in comparison to by means of hardening as you do not harden the whole cross-portion. Hence, along with the uncooked substance price, we can also help you save methods in producing.
Exclusive Homes
The mixture of a comfortable inside main with a challenging outer layer delivers unique homes as talked over in the earlier area. Circumstance hardening lets us to just take gain of these homes. Circumstance-hardened couplings are illustrations of components that supply sturdiness as perfectly as toughness. They can manage compact misalignments a lot far better than by way of-hardened pieces.
Diminished Content availability
When materials availability is an difficulty, we can decide for circumstance-hardened lower-carbon steel specially in non-important apps. Numerous spots do not have the necessary software steel grades available in different dimensions. The only way to obtain it, in that scenario, is to purchase a much even larger measurement than essential. So as a substitute of buying that, we can purchase low-carbon steel and get it circumstance-hardened for our programs.
Application-centered use
The application in some cases requires only a challenging surface area. In such conditions, rather of via hardening, we can go for just area hardening. Suitable examples are data files, bolts and gears.
In a file, for occasion, the tooth are doing all of the do the job. So it tends to make perception to use very low-carbon steel and just harden the surface. Performing this would be cheaper than applying resource steel or even through-hardening.
Let us grow on the example of a gear. A gear wants large hardness at the tooth to give it wear resistance. But it does not need by-hardening. In simple fact, it is suggested to retain the core soft to avoid sudden failure under load. A case-hardened equipment will allow us to combine flexibility and significant surface hardness into the identical component.
Situation Hardening Procedure & Strategies
The circumstance hardening principle is fairly straightforward. We want the surface area to type a tough construction regarded as martensite. But this structure sorts only when steel elements are quenched at large temperatures and presented that the carbon articles of steel alloy is substantial more than enough.
If the carbon written content is sufficient, we only have to have to heat and quench the part. But if the carbon articles is low or if we have to have intense hardness, factors these as carbon and nitrogen need to be additional to the material’s area. Let us now glance at the unique processes used to attain scenario hardening primarily based on the above-talked about ideas.
Heating and Quenching
Customarily, heating and quenching have been applied to have out hardening in a variety of metals. When we want to case-harden a metal, we can use a immediate oxy-gasoline flame on the steel element. In some conditions, induction heating is utilized. In both scenario, the floor temperature of the steel section rises speedily. This results in the crystal framework to improve from pearlite to austenite.
After a set temperature is arrived at, the part is cooled promptly, typically by immersing it in water. This alters the crystal construction when once more, this time from austenite to martensite which is a particularly challenging construction.
Considering the fact that only the floor undergoes the modify in the crystal framework, the portion hardens only at the area. But in get for the element to advantage from this system, there must be sufficient carbon in the authentic content. In the circumstance of minimal carbon material (<0.3%) in the metal element, this system will not generate favourable success.
Carburising
If the carbon degrees are down below .3%, we must include a lot more carbon to the aspect in advance of subjecting it to heating + quenching. Placing a section by way of the carburising procedure is a person way to do that.
In carburising, the steel element is heated in the presence of an external carbon resource for a established total of time. At substantial temperatures, the carbon from the carbonaceous material diffuses into the metal. Greater temperatures and lengthier warmth instances consequence in deeper absorption of carbon into the metal surface.
There are 3 key methods: Pack carburising, liquid carburising, and gas carburising. When compared to pack carburising, liquid and gasoline carburising are much better at diffusing carbon into the product. Carburising is commonly carried out at 930 °C (1700 °F).
After carburising will increase the carbon articles of the steel surface layer, we put it as a result of flame hardening or induction hardening to raise the hardness.
Nitriding
For a steel alloy that contains components these kinds of as aluminium, chromium and molybdenum, we can use nitriding for circumstance hardening.
The portion is heated in the existence of nitrogen gas and dissociated ammonia to type nitrides. The nitrides also boost the hardness of the material.
There are three key types of nitriding processes. These are salt bathtub nitriding, gas nitriding and plasma nitriding.
Nitriding generally operates with decreased temperatures as the portion is heated up to 620 °C (1150 °F). The for a longer time it is held at this temperature, the deeper the diffusion and subsequent hardening.
Cyaniding
Cyaniding is a sort of scenario-hardening approach that diffuses carbon and nitrogen in the existence of a cyanide-based salt. The aspect is initial heated up to 950 °C (1750 °F) for a predetermined length.
Just after adequate carbon and nitrogen are absorbed, the element is quenched adopted by rinsing to eliminate the residues of cyanide. The final step is especially significant as cyanide is a poisonous compound and wants to be addressed with care.
Carbonitriding
Carbonitriding refers to the addition of carbon and nitrogen to a slim layer of the steel area. It is equivalent to gasoline carburising but with an ammonia surroundings.
The presence of ammonia delivers the nitrogen for the process. The carbonitriding temperature is about 840 °C (1550 °F) which is between the nitriding and carburising temperatures. The material is then quenched in possibly oil or fuel.
The reduce temperature effects in fewer distortion all through quenching. The resultant product can have a hardness of up to 60 HRC. This hardness is better than what can be accomplished with the carburising method.
Carbonitrided elements also deliver superior effectiveness at elevated temperatures. Whilst carburised steel pieces begin losing their hardness over 200 °C, carbonitrided pieces keep their hardness a lot lengthier because of the stable nitride compound subtle in the matrix.
Most producers scenario-harden engine crankshafts by means of the carbonitriding system.
Ferritic Nitrocarburising
Ferritic nitrocarburising provides carbon and nitrogen to the steel when it is still in the ferritic stage. In the higher than processes, by heating the substance earlier mentioned the important temperature, the microstructure is changed from ferrite to austenite.
In ferritic nitrocarburising, we do not tactic this temperature. We expose the product to the carbon and nitrogen-wealthy ambiance even though it is nevertheless in the ferritic phase.
There are 3 major varieties of processes: salt tub ferritic nitrocarburising, gaseous nitrocarburising, and ion nitrocarburising.
Summary
Circumstance-hardened steel is a extensively made use of surface therapy method in the industry today. It is in particular valuable in applications wherever vibrations, shock hundreds, and misalignment are existing. Circumstance hardening gives outstanding hardness in these programs without having raising brittleness.
We hope that we were being able to give you an overview of the scenario hardening approach.

Welding joints are the connections involving two or extra pieces of metal (or plastic) that are established during the welding approach. The weld joint design and style enhances the weld composition, the welding strategy and the content. Employing distinct weld joints for a venture is vital as it is just one of the primary factors that will decide the power and good quality of the concluded merchandise.
Take a dive into the unique varieties of welding joints, every with its very own exclusive qualities, suited for numerous apps.
Welding Joint Types
Force, load, thickness, resistance and aesthetics are some of the contributing components when it arrives to analyzing appropriate welding joints for a project. These joints may also be influenced by the kind of welding course of action as some processes are greater suited for welding in sure positions.
There are five most important welding joint kinds utilized across the welding industry:
Butt Joint
Butt joints are a single of the most popular varieties of welding joints and are often used in the piping, construction, and fabrication sector. Flat items of metal are laid parallel with their edges touching or at a 135° to 180° angle from every other. Properly formed butt joints where by the weld metal completely penetrates the joint with entire root fusion realize superior mechanical strength, while poor welding tactics can guide to failure from incomplete penetration, burn up-via, cracking or distortion.
Butt joint welding necessitates minimal to no edge planning. Applications that demand edge planning of the edge joints would ordinarily require distinct bevel angles based on the project’s scope. The structure of a butt welding joint will tremendously count on the content thickness, backing content, edge preparing, and over-all in shape.
For thicker materials, a square butt joint may possibly not be equipped to do the trick any more and it becomes unavoidable to utilise some variety of groove to assure a audio weld with suitable penetration.
Butt joints can be subdivided into the adhering to groove welds:
Sq. groove
Single or double bevel groove weld
Solitary or double J-groove weld
One or double U-groove weld
Tee Joint
Tee joints are performed by welding two perpendicular items of metal, forming a T-form intersecting at somewhere around 90°. Tee joint is regarded as to be a type of fillet weld and they are also fashioned when welding a pipe onto a baseplate.
It is largely utilized on structural steel, products production, and tubing since it necessitates tiny to no planning while proficiently reaching best mechanical toughness. Fillet welds account for approximately about 70% of all joints developed by several arc welding procedures, this kind of as MIG, TIG and adhere welding.
Tee joints could be welded on 1 facet where the load will be utilized or at both of those finishes to realize optimum strength. The design and style of tee joints can make them vulnerable to lamellar tearing because it is restricted concerning the two workpieces.
Tee joint layout would differ relying on the material thickness, edge preparing, and get the job done angle. Challenging get the job done angles also exclude some forms of welding procedures.
Tee joints can be subdivided into these weld types:
Bevel groove weld
Fillet weld
Flare-bevel-groove weld
J-groove weld
Melt-through weld
Plug weld
Slot weld
Lap Joint
A lap joint is a modified butt joint more suited for supplies with different thicknesses. This is shaped by overlapping the metals, forming an angle of -5°. Lap joints are widespread in the fix and sheet metal industry, whereby skinny metals are used.
Welding joints using this strategy adds additional reinforcement to the weld, presented that it is thoroughly accomplished with no hole in between the overlapping metals. Corrosion and lamellar tearing are the top will cause of failure when utilizing this joint.
Listed here are the welding variations for lap joints:
Bevel-groove weld
Flare-bevel-groove weld
J-groove weld
Slot weld
Spot weld
Corner Joint
Corner joints are related to tee joints, with two metal bars forming a 90° in shape with each and every other at the corner, forming an L-condition. It is common for sheet metal welding and constructing different frames and tables.
There are two strategies when corner welding a joint, both an open up or closed corner is fashioned. Open corner joints kind a V-shape amongst the two metals, with the two metal edges touching each other. Closed corner joints are fashioned with a single edge of the metal touching the confront of the other metal. Though a shut corner joint is additional intricate than an open up corner joint, it usually delivers a bigger total mechanical toughness.
Form of welds applied for corner joints:
Edge Joint
Edge joints are equivalent to corner joints wherein two metals intersect at a common mating edge but have the two metals aspect by aspect. Both of the two workpieces may perhaps be bent at an angle relying on the application.
The sort of edge joint will depend on how the edge of the metals is well prepared. Some of these preparations involve chopping, grinding, or machining into several groove varieties that guide to various quantities of penetration. Depending on the task specifications, edge joints could also be welded only on the edge or all all-around.
An edge joint may perhaps be created working with these types of welds:
The Significance of Applying the Right Kind of Joint
Knowing weld joint style can make it an critical instrument for figuring out the achievements of any welding task. Deciding on the proper weld joint along with the equipment and the option of welding method and procedure is vital to reaching the most robust and strong joints.
It is essential to recognise and foresee the forces used to the workpiece, as it will certainly be just one of the deciding aspects whether or not the style is helpful. Integrating this into the joint structure will stop structural failure down the line and can help to accomplish weld integrity and excellent.

Electroplating is a common surface finishing process in the manufacturing industry to coat a material (substrate) with another metal. In recent years, the process has undergone many advances, making it much more accurate and capable of working with a wider range of materials.
In this article, we will explore the modern electroplating process to understand what it is, how it works, its benefits and limitations.
What Is Electroplating?
Electroplating is a manufacturing process in which a thin layer of metal atoms is deposited to another material through electrolysis. The metal added is known as the deposition metal, and the underlying material or workpiece is known as the substrate material.
By adding a layer of the desired metal, we can improve several physical, mechanical and chemical properties of the substrate, such as its strength, heat conductivity, electrical conductivity, abrasion and corrosion resistance.
Improving these properties can allow us to combine different metals to achieve properties that perfectly suit different applications.
How Does the Electroplating Process Work?
The electroplating process works on the principle of the electrolytic cell.
In this process, two metal rods are placed in an electrolyte. The rods act as electrodes when connected to the opposite terminals of a battery or power supply to create a potential difference. The electric current causes the electrolyte bath to disintegrate into dissolved metal ions, and the positively charged metal ions deposit on the negative electrode (cathode).
These positively charged ions are part of the electrolyte. As they get deposited on the cathode, their concentration in the electrolyte reduces. By choosing a suitable element for the anode, we can replenish the concentration of the positive ions.
For instance, if we need to coat brass with copper, the brass becomes the substrate. Connecting it to the negative terminal makes it the cathode. We use an electrolyte, such as a copper sulfate solution, that gives positive copper ions upon disintegrating. On the other end, we use a copper anode to replenish the electrolyte’s positive ions.
We can control the plate thickness, rate of metal deposition, surface finish, colour and many other factors by manipulating the process parameters. For example, using pure copper plates will give a better appearance than regular copper rods available in the market.
Using this process, the material can be coated with one or more metals.
Types of Electroplating Methods
Over the years, the electroplating process setup has evolved to suit different applications. By choosing a method in line with the application, the efficiency of the operation can be increased significantly.
To choose the right one, we must first understand the different types. Overall, electroplating methods can be divided into four major types. These are:
Mass plating
Rack plating
Continuous plating
In-line plating
Mass Plating
Barrel plating
As the name suggests, mass plating is used for mass-production applications. The method can handle a large volume of products that require thin coatings of metal.
A common type of mass plating method is known as barrel plating. In this method, the material to be coated (substrate) is dipped in a barrel containing the metal salt (electrolyte) and the anode of the coating metal.
The barrel plating setup is highly economical for small parts that need a uniform coating. As the barrel rotates, all the parts are cleaned, descaled and uniformly coated to a greater extent compared to rack plating.
This method is not recommended for parts that require a detailed finish without scratches and entanglement.
Mass plating is generally used for small but robust parts such as nuts, bolts and screws.
Rack plating
Rack plating
When the parts are larger than those suitable for mass plating, the rack plating method is used. In rack plating, the parts are mounted on racks and immersed in the chemical electroplating bath.
The rack plating process reduces the damage to delicate or fragile parts and coats the interior contours and deep crevices of parts, unlike mass plating.
This process is, however, more expensive than mass plating. But it makes up for it by providing a plated layer of much higher quality than a mass-plated product.
Rack plating is typically best for large, fragile and complex parts that require a plating of gold, silver, tin, copper or nickel.
Continuous plating
The continuous plating process is performed on exceptionally long parts, such as metal tubes, wires and strips.
In the case of thin strips, this process is also known as the reel-to-reel plating process. In this process, a long product is passed through the chemical bath at a specified rate. The end product’s quality is controlled by manipulating the process parameters and the time spent in the bath.
The reel of the product to be coated is uncoiled at the initial station, and once it passes the electrolyte/anode and gets coated, it is recoiled for easier storage and transport. Then further operations can be performed to stamp it into the required shapes.
In-line plating
The in-line plating method uses an assembly line for the metal plating operation. The metal passes through the various stations and automated machinery facilitates the chemical reaction.
Line plating is generally used for coating copper, zinc, chromium and cadmium. A variety of substrates can be coated with these metals through line plating. This method is relatively cheaper than other methods because a lower amount of chemicals is needed per piece.
Suitable Materials
Electroplating is a versatile process owing to the fact that it requires only one property in the substrate: electrical conductivity.
Since this property is exclusively available with metals (barring a few exceptions), we could initially use electroplating only for metals. But with the advent of conductive sprays and coatings, it is now possible to coat non-conducting materials such as plastic and wood too.
As a result, today, there are many more materials that can be electroplated. The substrate material can greatly vary depending on the application.
Silver or gold plating is often used to improve the appearance. To improve properties such as bacterial resistance and conductivity, copper plating is a favourite. Copper electroplating also offers increased malleability, lubricity and corrosion resistance.
Similarly, when we need to improve corrosion and wear resistance simultaneously, we go for nickel plating. Nickel also improves the appearance of the product.
Some other metals that are normally used for coating in electroplating are chromium, cadmium, zinc, iron and titanium.
But the substrate and the coating must be chosen carefully. Not all materials combine with each other. For example, steel cannot be plated with silver right away. It must first be plated with copper or nickel before silver plating.
Benefits
The first modern electroplating plant was set up in Hamburg in the late 19th century. The intention was to improve the appearance. But as science understood the mechanism and benefits of electroplating, its applications for non-decorative purposes became common.
Today, we understand the true breadth of electroplating benefits. Let’s list them down for a better overall understanding.
Electroplating improves physical properties such as colour, lustre and conductivity.
Colour and lustre provide cosmetic upgrades that are necessary for many day-to-day products as well as art applications.
Everyday appliances and kitchen products such as utensils, pans, cutlery, taps, kettles and other gadgets become much more attractive when coated with shinier metals such as copper, gold or silver. It also improves their functionality, as electroplated products are often easier to clean.
The appearance of artistic installations such as sculptures and figurines can also be improved by using electroplating. As a result, electroplating also finds use in art restoration and preservation projects besides new art creation.
Functionality can also receive a boost in technical applications involving electrical components such as antennas and integrated circuits. Although metals are already conductive, coating them with a better conductor improves the overall conductivity of the part while keeping costs low.
Costs are also reduced by the fact that non-metals can be used for electrical applications after electroplating. Besides having lower costs, non-metals also weigh less, which reduces the cost and difficulty related to the transport and storage of products.
Electroplating also improves mechanical properties such as tensile strength, wear resistance and durability, depending on the application.
The small increase in tensile strength is enough to bridge the gap between the SLA resins of 3D printing (plastics) and metal alloys. The distinct strength characteristics allow the use of electroplated materials in applications where previously metals would have had to be used.
The metal skin on a plastic product, besides making the product lighter, also imparts excellent flexural strength characteristics.
We can also improve the surface finish using electroplating. This makes the products easier to handle and reduces friction.
All these improvements increase the short-term performance while also lengthening the lifespan of the products.
Improved Chemical Properties (Corrosion, Chemical, UV and Radiation Resistance)
The chemical properties of a material can also be enhanced by using electroplating. Properties such as corrosion resistance, resistance to chemicals and UV light are crucial in certain applications such as medical implants.
Typically, medical implants depend on precious metal coatings of gold, silver, copper and platinum for their corrosion protection, electrical conductivity, heat dissipation, non-toxic and antibacterial nature.
Chemical and corrosion-resistant products are also required for harsh service environments where the product is exposed to chemicals, moisture and seawater.
Limitations
Electroplating has certain disadvantages that prevent its use in some cases. Let’s evaluate these to get a complete picture.
Complex process
The process is far from simple and can be difficult to carry out reliably. A process would have to be set with predetermined parameters to obtain parts of a consistent quality. Mistakes in preparation and pretreatment can lead to defects, poor quality and capability of finished parts.
Electroplating cannot be used for all material combinations, as they may not combine well with the plating solution.
Long plating time
The plating time can be excessively long in some cases. The metal deposition rate can be increased by either increasing the power supply or the concentration of the electrolyte or both. But this will cause uneven deposition, which can be a dealbreaker in some cases.
The benefits are limited to the surface
By its nature, electroplating is only limited to the surface. Once the surface layer is scratched off, the product can lose some or all of the benefits provided by the process.
Hazardous nature
The process releases gases due to the reduction at the cathode. If these gases are of a hazardous nature, they pose considerable risks for personnel in the vicinity.
Hexavalent chromium exposure from chrome plating is an apt example of how hazardous the electroplating process can be.
Wrapping It Up
Electroplating is nothing short of an engineering wonder. In the past, we could only use it on metals, but that is no longer the case. Today, we can electroplate plastics, ceramics and even organic materials such as leaves and flowers.
However, it still remains a very difficult process to execute consistently. This is why engineers and designers should turn to electroplating service providers for their expertise. Fractory’s sales engineers have plenty of experience in planning and executing custom projects, so don’t hesitate to get in touch.
FAQ
How do I identify the positive and negative terminals of the power supply in the electroplating solution?
It is very important to maintain the right polarity during electroplating. If for some reason you are not able to identify the anode (positive electrode) from the cathode (negative electrode), remember that the bubbles are generated on the cathode during the reaction.
This tells us that the electrode with the bubble formation is connected to the negative terminal of the power supply.
What is electroless plating?
Electroless plating works on the principle of an electrochemical cell. A chemical reaction causes the deposition of one material on another without the need for an electric current. The coating metal is usually a metal or a metal alloy and the substrate could be either a metal or non-metal such as plastic, ceramic, glass, etc.
What is electroforming?
The electroforming process refers to the use of electric current across a chemical bath to form solid models with intricate cavities. The process is similar to electroplating except that instead of a surface, we are building a solid article with a complex cavity.
It uses a template known as the mandrel. The mandrel is dipped in the electrolyte and the electrolytic reaction forms a layer of the deposition metal on the mandrel in the negative shape of the mandrel.
