CrN / CrCN – chrome nitride / chrome carbon-nitride

For a high level of adhesion

The chrome-nitride coating is characterized by the following properties:


Special features:

The relatively high hardness, in combination with a low level of brittleness allows the coating of thicker layers with good adhesion. This means an additional wear reserve for many applications. In areas where corrosion resistance is also required, as well as abrasion resistance, the CrN coating represents the ideal solution.

Deposition technology:

The application of the CrN layers is implemented by means of PVD technology. This allows the deposition of the layer on tool steels, HSS, cemented carbides or many other materials with temperatures up to 450° C.
