Heavy manganese phosphate coatings provide an attractive anti-galling, break-in/wear-in interface between rotating, sliding and meshing ferrous surfaces that will not flake off. Corrosion resistance to 900 hours per accelerated corrosion testing spec ASTM B117 can be achieved when standard supplemental oil is applied. Heavy manganese phosphate coatings are also used as a chemical conversion coating between ferrous substrates and a baked or air-dried solid film lubricant topcoats.
