BLACK OXIDE: A Conversion Coating
Black oxide is a conversion finish that provides essential protection – and a distinct black coloring – to ferrous metals by creating a chemical reaction within them. The chemical reaction allows a protective coating to be formed without increasing part dimensions, dulling the part’s luster, or altering the hardness of the metal. Because black oxide does not actually apply a coating that bonds to metal, it cannot chip or rub off. Metal that undergoes black oxide conversion also receives two more distinct advantages: dimensional stability and corrosion resistance. After black oxide, parts can withstand up to 96 hours of salt spray testing with the appropriate post treatment of a rust inhibitor.
As the coating becomes an integral part of the metal surface, there is no peeling, chipping or flaking. Black oxide can only be removed through mechanical or chemical means. Parts with black oxidation do not produce noxious fumes during welding. Black oxide does not reduce hardness. Black Oxide is an anti-galling surface that provides a lubricating layer during initial contact while work-hardened surfaces form.
