Within metals chemical conversion processes, phosphate coating represents one of the best anti-friction treatments, as it transforms the phosphate processed surface in an excellent base for lubrication and mechanical processing
In case of metallic components having to set each other within a mechanical working process (such as, for example, cold extrusion) the phosphate coating treatment allows to reduce micro-toughness thus enhancing the coordinate movement.
Manganese phosphate coating is one of the most widespread anti-friction treatments for ferrous metals, but not the only one: during project assessment phase only, it is possible to choose which type of phosphate coating treatment can guarantee best results.
