BALIMED CNI coated medical devices
BALIMED CNI coated MIS instruments

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
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.
