BALINIT CNI

BALINIT CNI is a very smooth sputtered Chromium Nitride (CrN) coating. It is very ductile and has a high oxidation resistance. It is the coating which can be produced in highest thicknesses (up to 50 µm). Mainly used for high temperature sliding applications like engine exhaust valves and piston rings. Smoothness, ductility and wear resistance makes BALINIT CNI also a powerful alternative to hard chrome plating for textile fibre guiding elements.

  • High oxidation resistance for high temperature applications
  • High ductility, high thicknesses possible
  • High textile fibre wear resistance
  • Alternative to hard chromium plating

General remark All given data are approximate values, they depend on application, environment and test condition.
*Dureza recubrimiento HIT [GPa] Measured by nano indentation according to ISO 14577. For multilayers the hardness of the different layers varies. Hardness can be adapted to the application.
**Coefficient of friction (dry) vs. steel Determined by ball-on-disc test in dry condition with an Steel ball according to ASTM G99. During run-in the given values may be exceeded.
****Max. service temp. [°C] These are approximate values out of the field. Due to thermodynamic laws there is a dependency of pressure in application.
