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
