BALINIT C STAR Perfect for soft base materials and components exposed to high mechanical loads

FDA approved food-safe coating.

BALINIT® C STAR is ideal for soft base materials. Its hard, tough chromium nitride-based metal layer guarantees optimal surface hardness and support (load-bearing capacity) for the superposed carbon coating (WC/C).

The WC/C coating offers outstanding adhesive wear protection, while its low coefficient of friction reduces the risk of surface fatigue and tribo-oxidation. The compact chromium nitride layer simultaneously enhances component corrosion resistance.

The result is a flawless, homogeneous coating of unique quality and adhesion.

These properties make it the ideal coating for components made of soft base materials, such as titanium, non-ferrous metals or stainless steel, high surface pressures, plain bearings and gearings. At the same time, BALINIT® C STAR is ideally suited for non-lubricated systems in clean rooms and, thanks to FDA approval, for food production applications.

  • Excellent protection against adhesive wear (scuffing)
  • Reduces surface fatigue
  • Reduces tribo-oxidation (fretting corrosion)
  • Increases load-carrying capability

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.
