BALINIT C STARPerfect 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.
