CERODEM® WCH
CERODEM® WCH is a diamond-like carbon with fine metal carbide inclusions. This enables the simple reduction of friction, surface fatigue and tribo-oxidation in a proven manner.
Advantages
- Increase in component service life and reduction in maintenance costs
- Lower friction leads to lower energy consumption
- Versatile application thanks to high temperature and corrosion resistance
- Improved product quality through consistent performance
