Abstract
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.
