The surface of the steel surface produces a layer of manganese phosphate film to form a chemical.
The manganese phosphate film is effective for enhancing the abrasion resistance of the turning and folding parts such as pistons, piston rings, cylinder liners, crankshafts, gears, etc.
It can avoid direct corrosion of the metal on the surface of the turning and folding parts, and prevent scorching and entanglement.
Good oil absorption performance, which helps the surface lubricity.
The film can eliminate the slight disappearance left by the mechanical action.
Excellent corrosion resistance, suitable for military products and automotive industry.
