Details of metal surface treatment.

Anodized metal or other insoluble materials are used as anodes, and the plated workpiece is made of cathode, and the cations of the coated metal are reduced to form the coating on the surface of the coated workpiece.
In order to eliminate the interference of other cationic ions, and to make the coating uniform and firm, it is necessary to electroplating bath with a solution containing metal cation of the coating to keep the concentration of metal cation in the plating.
The purpose of electroplating is to coat the base material with metal coating and change the surface property or size of the substrate.
Electroplating can enhance the corrosion resistance of metal (coating metal with corrosion resistant metal), increase hardness, prevent wear, improve electrical conductivity, lubricity, heat resistance, and surface appearance.
Electrophoresis electrophoresis electrophoresis coating in the Yin and Yang, applied to the voltage, the ions move to the cathode, take charge of the coating and the cathode surface generated by the basic function of formation of insoluble material, deposited on the surface.
Electrophoresis surface treatment: the characteristics of electrophoresis paint film has the advantages of uniform coating plump, and level off, smooth, electrophoresis paint film hardness, adhesion, corrosion resistance, impact resistance, permeability is better than other coating process.
Zinc-galvanizing is a surface treatment technology that is coated with zinc on the surface of metal, alloy or other materials for the purpose of aesthetics, rust prevention and so on.
Now the main method is hot galvanizing.
