Water plating
General electroplating (cold plating) refers to water plating, is the most common electroplating method, is an electrochemical process, the use of positive and negative electrodes, plus current in the plating bath, gold, silver, nickel, chromium, cadmium plating, electroplating solution pollution is very large. Water plating is divided into electroplating and electroless plating two, electroplating as a decorative surface, because there is high brightness, electroless plating surface is more gray, generally as an anti-corrosion coating. When electroplating, the plating metal as an anode, is oxidized into a cation into the electroplating solution; The metal products to be plated as the cathode, coating metal cation in the metal surface is reduced to form a coating. In order to eliminate the interference of other cations, and make the coating uniform, firm, need to contain coating metal cation solution electroplating solution, in order to keep the concentration of coating metal cation unchanged.
