               Do you know the process of gilding a watch  ?

 


     The method of plating is to cover the mercury with a thin layer of gold mercury, which is then heated to volatilize. To attach gold to a metal or other surface by electrolysis or other chemical means, forming a thin layer of gold.

     Electroplating is the process of coating a conducting body with a layer of metal using the principle of electrolysis. Electroplating is a surface processing method in which the pregold-plated cation of the pregold-plated metal is deposited on the metal surface of the substrate by electrolysis in a salt solution containing the pregold-plated metal as the cathode.

The performance of the coating is different from that of the matrix metal. According to the functions of the coatings, it is divided into protective coatings, decorative coatings and other functional coatings.

     When plating, the coated metal or other insoluble materials are used as anodes, and the workpiece to be plated is used as cathode. It can enhance corrosion resistance of metal (corrosion resistant metal is used in coating), increase hardness, prevent abrasion, improve conductivity, smoothness, heat resistance and appearance.
