Purpose: The aim of the research is the investigation of the mechanical properties of gradient coatings deposited by PVD technique (cathodic arc evaporation method) onto the substrate from the X40CrMoV5-1 hot work steel. Design/methodology/approach: The microhardness tests were made on the dynamic ultra-microhardness tester. Tests of the coatings' adhesion to the substrate material were made using the scratch test. The wear and friction tests were performed on a standard pin-on-disc device. Findings: The hard PVD gradient coatings deposited by cathodic arc evaporation method demonstrate the high hardness, adhesion and wear resistance. The critical load LC2, which is in the range 46-59 N, depends on the coating type. The friction coefficient for the investigated coatings is within the range of 0.30-0.90. Research limitations/implications: In order to evaluate with more detail the possibility of applying these coatings in tools steel, further investigations should be concentrated on the determination of the mechanical and tribological properties of the coatings. Originality/value: It should be stressed that the mechanical properties of the PVD coatings obtained in this work are very encouraging and therefore their application for products manufactured at mass scale is possible in all cases where reliable, very hard and abrasion resistant coatings, deposited onto tools steel substrate are needed.
