These terms all refer to the process of forming a black iron oxide on the surface of ferrous metals. Black oxide is a conversion coating formed by a chemical reaction produced when parts are immersed in the alkaline aqueous salt solution operated at approximately 285 degrees F. The reaction between the iron of the ferrous alloy and the hot oxide bath produces a magnitite (Fe3 O4) on the actual surface of the part. The black oxide process is a chemical conversion coating.
