STM7/16" 12" O.A.L. H.S.S. Aircraft Extension Drill High Speed Steel Black oxide is a chemical conversion process used to blacken the surface of a part without adding a thick coating. A chemical conversion process uses a chemical solution to force a reaction on the surface of the part rather than a plating or coating process which adds a thicker layer on top of the base material. Black oxide is most commonly done for ferrous metals (metals containing iron), but there are ways to black oxide other metals such as copper and stainless steel which are designed specifically to resist surface reactions.
