Thanks to the wide range of applications, Nitriding and Nitrocarburising processes are becoming more and more important. In addition to mechanical and technological characteristics, corrosion resistance is of vital importance for the functionality of surfaces.

The Corr-I-Dur® process not only enhances wear properties, but also significantly improves the corrosion resistance. Corr-I-Dur® has very little effect on distortion and dimensional changes of components. Compared to carburising and carbonitriding, dimensional changes are significantly lower.

Also depending on components’ geometry, standard corrosion requirements of most materials (> 96 h in the salt spray test DIN 50021 SS) are exceeded and Corr-I-Dur® is an environmental friendly alternative to galvanic layers.

The final corrosion resistance of components depends on various factors: material, roughness, surface contamination and dimensions.
