Abstract: The mechanical properties and tribological behaviour of a-C:H/TiCN/TiN coating were investigated at various sub-ambient temperatures for the first time using a newly developed low-temperature nanoindentation instrument. It has been found that the hardness and wear resistance of the a-C:H/TiCN/TiN coating increased with the decrease of the temperature.

Keywords: nanoindentation; scratch tests; low temperature; carbon coatings; nanoscratch; nanotechnology; mechanical properties; tribology; sub-ambient temperatures; diamond-like coatings; DLC; hardness; wear resistance.
