CHROME NITRIDE / CHROME CARBONITRIDE
- CrN / CrCN - FOR HIGHLY ELASTIC HARD MATERIAL COATINGS
Due to their high smoothness, improved ductility and high oxidation resistance during processing, chromium nitride layers are very attractive for industrial applications.
High smoothness, excellent wear resistance and ductile behavior with high elasticity of CrN / CrCN coatings
CrN can be deposited up to a thickness of 55 µm without detaching from the coated substrate. When combined with Cr, CrN is also an excellent interface material and is useful in multilayer structures to control stresses during the deposition of composite transition metal nitrides.

TO MEET THE HIGH MARKET AND CUSTOMER REQUIREMENTS
Numerous companies achieve remarkable improvements in the performance of tools and components through the coating materials and auxiliaries optimized by Avaluxe.
The Avaluxe cathode design facilitates the evaporation-assisted sputtering of CrN, which leads to a significant reduction in droplets and provides excellent surface properties.
Due to the ductile behavior of CrN, coatings of large components are possible, which increases the economic benefit, productivity and process reliability.
