Hemijska pasivnost
Kada se izvesni metali tretiraju određenim reagensima, npr. azotnom kiselinom ili nekim drugim oksidacionim agensima, reaktivnost prema reagensu koji je izazvao ovu promenu znatno je smanjena. Ovaj fenomen se naziva hemijskom pasivnosti (pasivizacijom, pasivitetom) i vrlo je sličan elektrohemijskoj pasivnosti.

uredi- ASTM (1. 3. 2010), ASTM A967: Standard specification for chemical passivation treatments for stainless steel parts (Rev 05e2 izd.), doi:10.1520/A0967-05E02. The most common commercial spec for passivation of stainless steel parts. Used in various industries; latest revision is active for new designs; legacy designs may still require older revisions or older standards, if the engineering has not been revisited.
- SAE (8. 7. 2011), AMS 2700: Passivation of corrosion resistant steels. (Rev D izd.). AMS specs are frequently used in the aerospace industry, and are sometimes stricter than other standards. Latest revision is active for new designs; legacy designs may still require older revisions or older standards, if the engineering has not been revisited.
- SAE (16. 2. 2005), AMS QQ-P-35: Passivation treatments for corrosion-resistant steel (Rev A izd.). AMS-QQ-P-35 superseded U.S. federal spec QQ-P-35 on 4 April 1997. AMS-QQ-P-35 itself was canceled and superseded in February 2005 by AMS 2700.
- U.S. government, QQ-P-35: Federal specification: Passivation treatments for corrosion-resistant steel (Rev C izd.). U.S. federal spec QQ-P-35 was superseded by AMS-QQ-P-35 on 4 April 1997 as part of the changeover instituted by the Perry memo. Both are now outdated; they are inactive for new designs, but legacy designs may still require their use, if the engineering has not been revisited.

- A standard overview on black oxide coatings is provided in MIL-HDBK-205, Phosphate & Black Oxide Coating of Ferrous Metals. Many of the specifics of Black Oxide coatings may be found in MIL-DTL-13924 (formerly MIL-C-13924). This Mil-Spec document additionally identifies various classes of Black Oxide coatings, for use in a variety of purposes for protecting ferrous metals against rust.
