CrN thin film, produced by our HCD (hollow cathode deposition) process, is availible up to 15 microns thick for your tool coating applications. CrN is produced by our NTH-1000 using the same ion plating process as TiN.

An AFM scan of CrN Thin-film

• Process temperature: 200-500&#176 C
• Thickness of CrN film: 2-20um
• Maximum deposition area: 200mm dia. X 400mm height
• Materials that we can coat with CrN:
  • machine tool steel
  • high speed steel
  • stainless steel
  • WC-Co

CrN is produced by the electron bombardment of a chromium source by hollow cathode discharge. The resulting evaporant reacts with nitrogen gas which is continually feed into the chamber. The resulting thin film can be CrN, Cr2N, or a mixture of both, depending on the mass flow rate of nitrogen used during the deposition.

Compared with TiN thin film, CrN offers a lower coefficient of friction as well as greater resistance to lock-up during movement. As such, CrN thin film is more suitable for tribological applications. CrN also offers greater thermal resistance and acid-base corrosion resistance than does TiN thin film.
