Black Oxide Coating
Black Oxide is a process which provides a conversion coating on iron which changes the surface of the material to a naturally occurring black iron oxide. The black iron oxide provides a pleasing aesthetic finish as well as a minimal change in surface dimensions (5 millionths of an inch). Though the black oxide does provide some corrosion protection by itself it is necessary to put a protective oil on this finish to keep it from rusting.
