All provided data are approximate values, depend on the application, environment and test conditions. Coating hardness HIT [GPa] measured by nano indentation according to ISO 14577. Hardness can be adapted to the application. Friction coefficient (dry) compared to the steel determined by ball-on-disc dry test with a steel sphere according to ASTM G99. During the running-in the indicated values may be exceeded. Maximum service temperature [° C] These are approximate values.
dianoir® is produced with a deposition system for ta-C DLC coatings patented by Argor-Aljba. The main advantages are:
- high wear and corrosion resistance
- uniform black-anthracite color
- non-toxic process and biocompatibility are optimal properties for the use of dianoir® in contact with the human skin
- special intermediate layer to ensure perfect adherence
