The manganese phosphate coating is generally used as anti-friction and self-lubricating treatment for components which have to set each other within cold working processes.

Manganese phosphate coatings (recognizable by their dark grey colour) allow to reduce the metal surface micro-roughness and to prepare a great support for lubricants and additives alike.

Together with this primary function, manganese phosphate coating treatments also have anti-corrosive properties, since the phosphate layer penetrates deeply and increase metal resistance
