Black coating or blackening is a conversion coating applied on steel, aluminium and other metals. It is used to improve corrosion resistance and minimize light reflection on parts.
Black oxide is not a deposit type coating, therefore unlike anodizing, it results in minimal dimensional change to the part.
Black oxide adds a mild layer of corrosion and abrasion resistance to fasteners. Like any material, black oxide treated fasteners can rust in the right environments.
