Description	Mechanické a tribologické vlastnosti naprašovaných MoSeC povlaků testovaných za vyšších teplot. (cs) Mo Se C films were deposited by sputtering from a C target with pellets of MoSe2. Besides the evaluation of the chemical composition, the structure, the morphology, the hardness and the cohesion/adhesion, special attention was paid to the tribological characterization. The C content varied from 29 to 68 at.% which led to a progressive increase of the Se/Mo ratio. As a typical trend, the hardness increases with increasing C content. The coatings were tested at room temperature with different air humidity levels and at temperatures up to 500 oC on a pin-on-disc tribometer. The friction coefficient of Mo-Se-C coatings increased with air humidity from ~0.04 to ~0.12, while it was as low as 0.02 at temperature range 100-250 oC. The coatings were very sensitive to the elevated temperature being worn out at 300 oC due to adhesion problems at coating - titanium interface.
