Firearm Blueing and Browning - R. H. Angier, Ned Schwing - books

Bluing is a passivation process in which steel is partially protected against rust , and is named after the blue-black appearance of the resulting protective finish. True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite Fe 3 O 4 , the black oxide of iron. Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanic action. A distinction can be made between traditional bluing and some other more modern black oxide coatings, although bluing is a subset of black oxide coatings. In comparison, rust , the red oxide of iron Fe 2 O 3 , undergoes an extremely large volume change upon hydration; as a result, the oxide easily flakes off causing the typical reddish rusting away of iron. It is a difficult product to apply evenly, offers minimal protection and is generally best used for small fast repair jobs and touch-ups. This method was adopted by larger firearm companies for large scale, more economical bluing.
