Detailed

Protective oxide film is formed on the surface of iron and steel parts through oxidation treatment. The main component is magnetic iron oxide (Fe3O4). The color of the film is generally black or blue black. Cast steel and silicon steel are brown or black brown. Oxidation treatment methods include alkaline oxidation, alkali free oxidation and acid oxidation. It is often used for the protection and decoration of machinery, precision instruments, meters, weapons and daily necessities. Dalian surface oxidation galvanizing processing Co., Ltd

Black oxidation treatment is a common means of chemical surface treatment. 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. The surface blackening treatment of steel parts is also called bluing. Black oxidation treatment, because it can eliminate reflection, is a surface coating treatment method commonly used by military knives.

In order to improve the anti rust ability of steel parts, the surface of steel parts is oxidized into dense and smooth Fe3O4 with strong oxidant. This thin layer of Fe3O4 can effectively protect the interior of steel parts from oxidation. Ferric oxide oxidized at high temperature (about 550 ℃) is sky blue, so it is called bluing treatment. Fe3O4 formed at low temperature (about 350 ℃) is dark black, so it is called blackening treatment. In weapon manufacturing, bluing is commonly used; Blackening is commonly used in industrial production.
