BALINIT DLC STAR Diamond-like carbon (DLC) coating with Superior Tribological ARrangement (STAR)

Star Tappet
BALINIT DLC STAR coated for diesel injector
BALINIT DLC STAR coated for collet chucks

BALINIT® DLC STAR is a modified diamond-like carbon (DLC) coating with enhanced load bearing capacity. An exceptionally hard, durable metal-based layer (chromium nitride) provides the required surface hardness and increases the load-bearing capacity of the tribologically effective carbon coating. BALINIT DLC STAR has even higher tribological performance than BALINIT C, BALINIT C STAR and BALINIT DLC. It is therefore used for the highest loaded components in diesel injection systems and engine components.

Coating material CrN / a-C:H
Coating technology PACVD
Coating colour black
Coating hardness HIT [GPa]* ~15-25
Coefficient of friction (dry) vs. steel** 0.1 - 0.2
Max. service temp. [°C]**** 300
Process temperature [°C] < 250
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.
