Electroplating, also known as electrochemical deposition or electrodeposition, is a process that involves coating a solid substrate with a thin layer of metal through the reduction of metal cations using direct electric current.Electroplating is widely used in industry and decorative arts to enhance surface qualities such as abrasion resistance, corrosion resistance, reflectivity, and appearance. It's used to build up thickness on undersized or worn-out parts (electroforming) In electronics, it deposits copper for printed circuit boards and interconnects in integrated circuits. Electroplating can also purify metals like copper.
