Electroplating is a process of applying a thin layer of metal on another metal surface by using an electric current. Electroplating can improve the appearance, durability, conductivity, and corrosion resistance of metal objects. Electroplating services are offered by various companies that specialize in different types of metals, finishes, and processes.
What are the Benefits of Electroplating Service
Electroplating service is a process of applying a thin layer of metal on another metal surface by using an electric current. Electroplating service can provide many benefits for different industries and applications, such as:
➤ Creating a protective barrier: By coating your component in a less reactive metal, electroplating service makes it more resistant to tarnishing and corrosion. It can also increase heat resistance and make the piece stronger against impacts and shocks if the underlying metal is brittle.
➤ Reducing friction: With a plating of nickel, you can make your components slide more easily across adjacent surfaces, without heating or scraping.

➤ Conducting electricity: Plating with silver can enhance electrical conductivity, making it a highly-effective process for the manufacturing of electronics and electrical components.
➤ Absorbing excess hydrogen: Plating with palladium can absorb excess oxygen that commonly results during the manufacturing of catalytic converters for automobiles. This can improve catalytic converter performance.
➤ Preventing formation of whiskers: A zinc-nickel alloy can prevent the formation of sharp protrusions known as whiskers that can occur during certain types of manufacturing operations. Damage caused by arcing and shorts in electrical parts and components due to whiskers breaking away from materials can be significantly reduced.
➤ Resisting heat: Plating processes such as gold or zinc-nickel are capable of withstanding extremely high temperatures. Plating with these metals protect engine parts and components from damage caused by extreme temperatures, which can increase their lifespan.
➤ Being magnetic: Electroless nickel plating is commonly used in magnetic applications such as the manufacturing of computer hard drives. Magnetic properties make it easier for discs to be read.
➤ Increasing hardness: Electroplating is sometimes used to make brittle materials stronger and more durable. Plated surfaces are less susceptible to damage when struck or dropped, which can increase their lifespan.

➤ Absorbing light and energy: Black electroless nickel plating absorbs the light and energy essential to many manufacturing processes in industries such as aviation, automotive and aerospace.
➤ Enhancing appearance: Jewelry is often plated with a thin layer of a precious metal to make it more lustrous and attractive to potential buyers. Manufacturers have a cost-effective way to make products more aesthetically appealing. Jewelers can sell products that look like pure gold or other precious metals at a much lower price.
What are the disadvantages of electroplating?
Electroplating is a process of applying a thin layer of metal on another metal surface by using an electric current. Electroplating can improve the appearance, durability, conductivity, and corrosion resistance of metal objects. However, electroplating also has some disadvantages, such as:
➤ Cost: Electroplating can be a costly process, especially for large or complex objects. The cost of electroplating depends on the type and amount of metal used, the quality and composition of the plating solution, the equipment and labor required, and the environmental and safety regulations that need to be followed.
➤ Environmental impact: Electroplating can produce hazardous waste and byproducts that can be harmful to the environment if not properly disposed of. Some of the substances used in electroplating, such as cyanide, chromium, nickel, and cadmium, are toxic and carcinogenic. They can contaminate the soil, water, and air, and pose a risk to human and animal health.

➤ Limited thickness: The thickness of the electroplated layer is limited by the thickness of the substrate and the plating process itself. Electroplating works on a molecular level, and the coating may be extremely thin. This means that either the coating has to be very thin, or multiple coats have to be applied to achieve the desired thickness. Both of these options have drawbacks, such as increased cost, time, and complexity.
➤ Uniformity: Electroplating may not result in a uniform coating of the metal on the object. The coating may be lumpy, uneven, or have gaps or defects. This can affect the performance and appearance of the object. To avoid this, the object has to be carefully prepared, cleaned, and activated before electroplating. The plating solution has to be maintained at the optimal temperature, concentration, and agitation. The electric current has to be controlled and adjusted. The object has to be rinsed and dried after electroplating. All of these steps require skill and precision, and may still not guarantee a perfect coating.
➤ Brittleness: Electroplating may make the coating more brittle and prone to cracking. This is especially true for some metals, such as chrome. The coating may form microcracks, which can let in impurities and cause corrosion or peeling. The coating may also crack or flake off due to thermal expansion, mechanical stress, or wear and tear. To prevent this, the coating has to be compatible with the substrate, and the plating conditions have to be optimized. Sometimes, additional treatments, such as heat treatment, polishing, or lacquering, may be needed to improve the durability and appearance of the coating.
TECVINA has been granted permission to construct an electroplating system in the northern region of Vietnam. Furthermore, TECVINA has a team of chemical engineers who can receive plating technologies methodically.
