The paper compares the abrasion and erosion resistance of two high-alloy tool steels, EN X153CrMoV12 and Böhler K390 MICROCLEAN, coated with multilayer coatings TiN / TiCN and TiN / Ti-B-N. Multilayer coatings were applied to hardened and tempered samples by pulsed direct current (DC) plasma-assisted chemical-vapour deposition (PACVD) process in the Rübig PC 70/90 industrial vacuum oven. The mechanical properties of the coating were tested by calotest, Rockwell-C indentation test and the test of fracture toughness and microhardness. Abrasion resistance was tested by the ""Dry Sand/Rubber Wheel” method. Erosion resistance was tested by exposing the surface of the samples to a jet of fine sand particles at an angle of incidence of 90 degrees for 60 min. Worn surfaces were analyzed with a light and scanning electron microscope. It was found that increased resistance to abrasion and erosion wear is achieved on samples with higher substrate hardness and higher hardness, fracture toughness and better adhesion of the coating. Based on the test results, a mathematical model for predicting the loss of coating mass after sand blast erosion was proposed.
