Electroplating is the process of plating a thin layer of other metals or alloys on some metal surfaces using the principle of electrolysis, is the use of electrolytic action to make metal or other material parts of the surface of a metal film to attach a layer of technology to prevent metal oxidation (such as rust), improve wear resistance, conductivity, reflective nature, Corrosion resistance (copper sulfate, etc.) and enhance the appearance of the role. The outer layers of many coins are also plated.
Electroplating, plating metal or other insoluble materials to do the anode, the workpiece to be plated to do the cathode, the cation of the coating metal to be plated on the surface of the workpiece is reduced to form a coating. In order to eliminate the interference of other cations, and make the coating uniform and firm, the plating solution is required to do the plating liquid to maintain the concentration of the metal cation. The purpose of electroplating is to coat the substrate with a metal coating to change the surface properties or dimensions of the substrate. Electroplating can enhance the corrosion resistance of metal (coating metal using corrosion-resistant metal), increase hardness, prevent abrasion, improve conductivity, smoothness, heat resistance and surface beauty.
