What is black phosphate coating? – Moorejustinmusic

2019-10-10  What is black oxide process? 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. The result of this chemical reaction is the formation of black iron oxide, magnetite (Fe3O4), on the surface of the metal being coated.

Black Oxide versus Black Phosphate - Finishing

2011-2-15  2003. A. Black oxide is an exceptionally thin process which, as the name implies, is an iron oxide film. It is formed by putting iron parts into a very hot and very strong solution of caustic soda with nitrates and other ingredients. Black phosphate, as I understand it and depending on who is selling it, is either a color variation on a standard phosphatized coating achieved with either a ...
