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.
Argor a-C presents the following advantages:
- suitable for machine components and subject to friction wear
- low process temperature, which allows for a wider range of substrate materials
- wide application field in the machines of textile sector
