    Phosphating is a surface treatment process in which a chemical reaction forms a film on the surface (phosphating film).

    Phosphating process is mainly used on the metal surface, the purpose is also to provide a layer of protective film for the metal surface, so that the metal and air isolation, to prevent its corrosion; Can also be used for some products before painting the bottom, with this layer of phosphating film can improve the adhesion and corrosion resistance of the paint layer, improve the decorative so that the metal surface looks more beautiful, and can also play a role in the lubrication of some metal cold processing.

    After phosphating treatment can make the workpiece in a long time will not oxidize rust, so phosphating treatment is widely used, is also a commonly used metal surface treatment process, in the automobile, shipbuilding, machinery manufacturing and other industries more and more applications.
