The oxide film(Fe3O4) formed on a nitriding layer (compound layer) is black, is glossy and is uniform. And it has combined with the nitriding layer and does not have the worries about exfoliation, either.The corrosion resistance of Oxy-Coat of nitriding-oxidizing compound layer in comparison with nitriding improves remarkably by pit closing (effect) of an oxide film. In addition, it also has the characteristics, such as wear resistance, attrition resistance, low friction, etc. |
