Their physical and mechanical properties, as well as tribotechnical characteristics have been studied. The coatings are characterized by a columnar structure and their hardness reaches 51.02GPa. The adhesion strength of the coatings has also been studied, the coefficient of friction of the system “coating – Al2O3“ is 1.1.The results of tribological tests at high temperature showed that at 460 °C coatings had greater wear resistance, lower coefficient of friction compared to similar tests of coatings at 20 °C.These coatings are perspective as protective coatings for friction pairs and cutting tools. popup.nrat_date 2025-05-12 Close
