In the process of electroplating manufacturing, the coated metal or other insoluble materials are used as the anode, the workpiece to be plated is used as the cathode, and the cation of the group to be gilded is restored to form the coating on the surface of the workpiece to be plated. It can enhance the corrosion resistance of metals (coated metals are mostly corrosion-resistant metals). Increase hardness, prevent wear, improve electrical conductivity, smoothness, heat resistance and surface beauty.

Electrolysis is used to deposit good adhesion on mechanical products. However, metal coating techniques vary in performance and substrate. The electroplating layer is uniform and generally thinner than the hot-dip layer, ranging from one micron to tens of microns. Through electroplating, decorative protection and various functional surfaces can be obtained on mechanical products, and can also be repaired. Repeated wear and machining of the wrong workpiece.
