%X Purpose: The paper presents the results of the mechanical and tribological properties of the CrN and TiN/(Ti,Al)N PVD coatings deposited onto plasma nitrided hot work tool steel X37CrMoV5-1 type.Design/methodology/approach: Tests of the coatings¡¯ adhesion to the substrate material were made using the scratch test. The surfaces¡¯ topography, structure of the PVD coatings were observed on the scanning electron microscopy. Wear resistance tests with the pin-on-disc method were carried out on the CSEM THT (High Temperature Tribometer).Findings: The results showed that the duplex TiN/(Ti,Al)N coating exhibited higher hardness, very good adhesion and better wear resistance in the elevated temperature as compared to the duplex CrN coating.Practical implications: The investigation results will provide useful information to applying the duplex PVD coatings for the improvement of mechanical properties of the hot work tool steels.Originality/value: The very hard and antiwear PVD coatings deposited onto hot work tool steel substrate are needed.
