Phosphating Treatments

Eurolls has installed in 2014 a new galvanic plant for Mn phosphating.

Phosphating is a surface conversion treatment that makes a chemical modification to the physicochemical properties of the surface of a metal. The process is based on the immersion of a part in a bath of phosphates and phosphoric acid. This creates a uniform layer of crystals chemically bonded to the substrate which enhances the characteristic of the materials itself.

Specifically, manganese phosphating, results in the formation of a dark gray coating, that is very resistant to corrosion and wear. By acting on the lubrication and the roughness, the phosphate layer reduces the friction between surfaces of mechanical components in reciprocal sliding. Eurolls covers all the details of this production process in order to provide protection and corrosion resistance on the components.
