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

BALIMED DLC is characterised by important functional properties: the black, matt coating helps surgeons to work reflection-free under the bright surgical lighting. In addition, BALIMED DLC does not react chemically with other substances. The coating is extremely wear-resistant and maintains the cutting sharpness of surgical instruments.

  • Suitable for all surgical instruments
  • Black anti-glare coating
  • Chemically inert (minimised reaction with other substances)
  • Low friction and high abrasion resistance
  • Improves the edge retention of surgical instruments
BALIMED DLC
Coating material 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.
