The difference is immersion in boiling water for bluing. The rust then turns to black-blue Fe 3 O 4. Many older browning and bluing formulas are based on corrosive solutions (necessary to cause metal to rust) and often contain cyanide or mercury salts solutions that are especially toxic to humans.
No. 61 (Rust and Blue) is a 1953 painting by the Russian-American Abstract expressionist artist Mark Rothko. The work was first exhibited at the Museum of Modern Art , New York in 1961 [ 1 ] but is now in the collection of the Museum of Contemporary Art, Los Angeles . [ 2 ]
There are aftermarket electronic "rustproofing" technologies claimed to prevent corrosion by "pushing" electrons into the car body, to limit the combination of oxygen and iron to form rust. The loss of electrons in paint is also claimed to be the cause of “paint oxidisation” and the electronic system is also supposed to protect the paint. [4]
The NaOH (caustic soda) and elevated temperature cause Fe 3 O 4 (black oxide) to form on the surface of the metal instead of Fe 2 O 3 (red oxide; rust). While it is physically denser than red oxide, the fresh black oxide is porous, so oil is then applied as post treatment to the heated part, which seals it by "sinking" into it.
Glock 17 pistol with a black Parkerized topcoat.

The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
