What Is Electroplating?

Electroplating is the process of using electrodeposition to coat an object in a layer of metal(s). Engineers use controlled electrolysis to transfer the desired metal coating from an anode (a part containing the metal that will be used as the plating) to a cathode (the part to be plated).

The anode and cathode are placed in an electrolyte chemical bath and exposed to a continuous electrical charge. Electricity causes negatively charged ions (anions) to move to the anode and positively charged ions (cations) to transfer to the cathode, covering or plating the desired part in an even metal coating. Electroplating takes a substrate material (often a lighter and/or lower-cost material) and encapsulates the substrate in a thin shell of metal, such as nickel or copper.

Electroplating is most commonly applied to other metals, because of the basic requirement that the underlying material (the substrate) is conductive.

The Benefits of Electroplating

Electroplating offers many benefits, including increased strength, lifespan, and conductivity of parts. Engineers, manufacturers, and artists capitalize on these benefits in a variety of ways.

Engineers often use electroplating to increase the strength and durability of various designs. You can increase the tensile strength of various parts by coating them in metals such as copper and nickel. Place a metallic skin on parts and you can improve their resistance to environmental factors like chemical exposure and UV light for outdoor or corrosive applications.

In the medical community, electroplating is used to make medical implants that are corrosion-resistant and can be properly sterilized.

Electroplating is an effective way to add cosmetic metal finishes to customer products, sculptures, figurines, and art pieces. Many manufacturers also choose to electroplate a substrate to create more lightweight parts that are easier and cheaper to move and ship.

Electroplating also offers the benefit of conductivity. Because metals are inherently conductive, electroplating is a great way to increase the conductivity of a part. Antennas, electrical components, and other parts can be electroplated to increase performance.
