Blueing

Blueing, named after the blue-black color of protective finish, is a passivation process in which steel substrate is partially protected against rust.

Blueing helps to maintain the metal finish by resisting tangential scratching, but parts still need to be properly oiled to prevent rust. Blueing, being a chemical conversion coating, is not as robust against wear and corrosion resistance compared to plated coatings.
