In-process Post-Nitriding/Nitrocarburizing Oxidation
When resistance to atmospheric corrosion and an attractive black finish are the main requirements, ONC® is the best technology.
ONC® is a clean technology that in many instances can replace chrome plating and salt bath nitriding with their inherent problems of pollution and cost. Depending on the type of steel, parts treated with the Nitreg® + ONC processes can easily pass well over 200 hours of salt-spray test per ASTM B117 before the first corrosion spot appears.

Oxynitriding / Oxynitrocarburizing transforms the very top portion of the white layer obtained with either Nitreg® or Nitreg®-C technologies into a complex spinel type structure consisting mostly of Fe3O4 type of iron oxide. As a result, the post-nitriding oxidation treatment has a net effect of enhancing the corrosion resistance of an already nitrided component. This integrated process (i.e. Nitreg® + ONC® or Nitreg®-C + ONC®) simultaneously enhances corrosion and wear resistance of steel, while giving the surface an attractive dark or black appearance, expressly desired by many customers.
Any steel can benefit from this technology.
