The black oxide process is a chemical conversion coating. This means that the black oxide is not deposited on the surface of the substrate like nickel or zinc electroplating.
In most operations where the corrosion resistance of finished workpieces must be especially high, conversion coatings are applied using zinc phosphate.
Manganese phosphate coating has the highest hardness and superior corrosion and wear resistances of general phosphate coatings.
