DLC coatings on camshafts and other valve train parts
Reducing friction and wear in motorsports
BALINIT CAVIDUR-coated for piston ring
BALINIT CAVIDUR-coated for tappet
BALINIT CAVIDUR-coated for valve

Components with diamond-like carbon (DLC) coatings have become well established in racing series such as NASCAR, Formula 1, WRC and DTM through reduced friction, increased wear resistance and extended lifetimes. BALINIT® CAVIDUR is the ideal DLC coating for valve train components. Motorbike and motocross components have moreover been optimized by this coating for more than 20 years. DLC coatings, such as BALINIT® CAVIDUR, are just one step in the development of high performance engines. Without them though, today´s high loads and performances wouldn´t be conceivable.

  • Increased performance and reliability
  • Significantly reduced friction and wear
  • Extended component lifetimes
Coating material TiN + a-C:H
Coating technology PACVD
Coating colour black
Coating hardness HIT [GPa]* ~25-35
Coefficient of friction (dry) vs. steel** 0.1 - 0.2
Max. service temp. [°C]**** 350
Process temperature [°C] 250 - 350
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.
