About traditional Oxidation / Blackening Chemicals

  Oxidation chemicals are also called as oxidation salts or blackening salts. Oxidation treatment forms a dark colored corrosion resistant coating on iron, steel and die castings. After coating, metal parts go into protective lubrication for enhanced corrosion protection. The treatment is made in strong alkaline solution at 135-145°C degree of temperature. Coating is made while treatment solution is boiling. But the traditional blackening is toxic.
