Black oxide or blackening is a conversion coating for ferrous materials, ... Applications for cold black oxide process include tooling and architectural finishing on ...
Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanic action. In colloquial use, thin coatings of black oxide are often termed "gun bluing", while heavier coatings are termed "black oxide". Both refer to the same chemical process for providing true gun bluing.

In the process of bluing, an oxidizing chemical reaction on an iron surface selectively forms magnetite (Fe 3 O 4), the black oxide of iron (as opposed to rust, the red oxide of iron (Fe 2 O 3)). Black oxide provides some protection against corrosion if also treated with a water-displacing oil to reduce wetting and galvanic action.
