The Basic Meaning Of Electroplating

Plating, metal plating anodes or other insoluble material, workpiece to be plated cathode coating of metal cations were restored to form coatings on the surface of the workpiece to be plated. To exclude the interference of other cations, and uniform coating, solid, need to do plating coating containing metal cations in solution, to keep the coating of metal cations concentrations remain unchanged. 

The purpose of plating is plated with metallic coatings on a substrate, nature or size change the surface of the substrate. Corrosion resistance of electroplated metal (metal coating corrosion resistance of metal), increase hardness, abrasion prevention, improve conductivity, smoothness and heat resistance and surface appearance.
