Examination of the phase and chemical composition of ion-plasma coatings on R18 high-speed tool steel after short-term heating
Analytical thermodynamic examination and subsequent experimental verification by the methods of local analysis, including x-ray and Auger spectroscopy, showed that it is possible to control the oxygen, carbon, nitrogen content of the coating based on titanium nitride on the high-speed tool steel in short-term thermal (to 800°C) shocks in air. Results show that in addition to TiN, compounds TiO1.75, TiO2, and TiC can also form in the coating, whereas Cr2N can form in the substrate. the possibility of formation of the new phases in the surface layer makes it possible to change its properties in a wide range, including the friction coefficient, hardness, corrosion resistance, etc.
