Black Oxide

What Is Black Oxide

Black oxidation treatment is a common means of chemical surface treatment, it is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. The principle is to produce an oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. Blackening treatment can be adopted when the appearance requirements are not high, and the surface of steel parts can be blackened. Black oxidation treatment refers to a surface coating treatment method commonly used by military knives because it can eliminate reflection.
