MIL-C-13924C, MILITARY SPECIFICATION: COATING, OXIDE, BLACK, FOR FERROUS METALS (09 JUN 1980) [S/S BY MIL-DTL-13924D]., This specification covers black oxide coatings applied to ferrous metals (wrought iron, carbon, low alloy, and corrosion resistant steels). Black oxide coatings, with or without a supplementary preservative treatment, may be used where a black surface is required. Only very limited corrosion protection, under mildly corrosive conditions, is obtained as a result of black oxide coating.
