Black Phosphated Details

The purpose of phosphating provides protection to the base metal and prevents the metal from being corroded to a certain extent; it is used for primering before painting to improve the adhesion and corrosion resistance of the paint layer; and to reduce friction and lubrication in the metal cold working process.

Phosphating treatment of metal surface is a common pretreatment technology. In principle, it should be treated by chemical conversion membrane, which is mainly used for phosphating of metal surface.

Phosphorification can also be applied to non-ferrous metals (such as aluminum and zinc). Metal surface phosphating is a chemical and electrochemical reaction to form a phosphate chemical conversion film. The phosphate conversion film formed is called a phosphate film. Metal surface phosphating is a simple, reliable, low-cost, and easy-to-use process for greatly improving the corrosion resistance of metal surfaces, and is therefore widely used in actual production.

The modern phosphating process is generally degreasing → washing → descaling → surface adjustment → phosphating → washing → drying. This paper mainly explains the fifth process in the phosphating treatment of metal surface, the phosphating process.
