In order to extend the service life of medical devices, in particular their moving parts must be protected against abrasion and corrosion. BALIMED CNI is a very smooth and temperature resistant coating fulfilling optimally these requirements.

  • Low friction
  • Reduces galling
  • High oxidation resistance for high temperature applications
  • Chemical resistant
  • Highly wear resistant
  • Aesthetic appearance of metallic colour
BALIMED CNI
Coating material CrN
Coating technology Sputter
Coating colour Silver-grey
Coating hardness HIT [GPa]* 18 +/- 3
Coefficient of friction (dry) vs. steel** ~0.5
Max. service temp. [°C]**** 700
Process temperature [°C] < 250
General remark All given data are approximate values, they depend on application, environment and test condition.
*Coating hardness 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.
