This paper deals with the evaluation of tribological properties of PVD coatings which are mainly used as wear resistance coatings. The aim of the work was to compare the tribological behaviour of TiCrN and TiAlCrN coatings deposited on the steel substrate using the technology of reactive cathode vapour deposition. The dry sliding wear of coatings has been investigated against tungsten carbide (WC) counterpart. The course of the friction coefficient indicated better sliding properties TiAlCrN with value 0.605 compared to TiCrN with friction coefficient value 0.877. The depth of worn-out surface amounted to about 2/3 of the worn-out surface of TiCrN coating. The surface of the WC ball showed higher roughening after tribo test of TiCrN.
