Electroplating bbc
WebElectroplating is also known as electrodeposition. As the name suggests, the process involves depositing material using an electric current. This process results in a thin layer of metal being deposited onto the surface of a workpiece called the substrate . Electroplating is primarily used to change the physical properties of an object.
