|Abstrakt EN:||TiCN coatings are usually deposited by the CVD or PVD method and are testified with dynamically loaded parts. CVD deposition proceeds during high temperatures and the coated parts are necessary to be tempered then. It is difficult to keep the wanted proportions at the very presice parts. That is why these coatings are examined to deposit by low temperature methods PVD and PACVD. The samples deposited in various coating centre are compared in this paper. The thickness, roughness and chemical constitution of coatings are evaluated. The nanoindentation measurements and the tribological tests by high temperataure pin-on-disc tribometer were both realized. Dynamical behaviour of the coaatings was evaluated on the dynamic impact tester.|
