Electroplating is the process of using the principle of electrolysis to coat a thin layer of other metals or alloys on the surface of certain metals. Such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics. The outer layers of many coins are also electroplated.

During electroplating, the plated metal or other insoluble material is used as the anode, the workpiece to be plated is used as the cathode, and the cations of the plated metal are reduced on the surface of the workpiece to be plated to form a plated layer. In order to eliminate the interference of other cations and make the coating uniform and firm, a solution containing metal cations in the coating should be used as the electroplating solution to keep the concentration of the metal cations in the coating unchanged.
