Manganese Phosphate Coating

Manganese phosphate coating is a surface treatment widely preferred for metal components operating in lubricated environments, particularly in the automotive and defense industries.

This process produces a dark, near-black surface finish and is applied at elevated temperatures with manganese activation. After treatment, components are coated with protective oil, which enhances corrosion resistance and ensures long-lasting lubrication retention on the surface.

Compared to zinc phosphate, manganese phosphate forms a thinner coating layer while retaining oil more effectively. This reduces friction and minimizes wear, improving the overall performance of moving parts.
