Chemistry:Black oxide - HandWiki

The caustic soda and elevated temperature causes Fe3O4 (black oxide) to form on the surface of the metal instead of Fe2O3 (red oxide (rust)). While it is physically more dense than red oxide, the fresh black oxide is porous, so oil is then applied to the heated part, which seals it by "sinking" into it.Chemistry:Black oxide - HandWikiThe caustic soda and elevated temperature causes Fe3O4 (black oxide) to form on the surface of the metal instead of Fe2O3 (red oxide (rust)).
