BALIMED DLC STAR Important functional properties – excellent anti-glare and chemically inert

BALIMED DLC STAR coated MIS instruments

BALIMED™ DLC STAR is characterized by important functional properties: The black, matte coating helps surgeons to work reflection-free under the bright surgical lighting. In addition, BALIMED™ DLC STAR provides enhanced wear protection under high loads, as well as improved friction reduction in complex tribosystems. The coating maintains the cutting sharpness of surgical instruments and thus prolongs their service life.

  • Suitable for all surgical instruments
  • Excellent black anti-glare coating
  • Chemically inert (minimized reaction with other substances)
  • Low friction and high abrasion resistance
  • Improves the edge retention of surgical instruments
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.
