CrN / CrCN
CrN / CrCN — chrome nitride / chrome carbon-nitride For a high level of adhesion
CrN exhibits good sliding properties with minimal lubrication. The high hardness and very low brittleness allow thicker CrN coatings with very good adhesion to the substrate.
The chrome-nitride coating is characterized by the following properties:
- High hardness and adhesion.
- Very good chemical resistance.
- High-temperature resistance in air
- Thicker layers possible
- Low coefficient of friction against steel
