Abstract: | In this work, the element and phase compositions and mechanical properties of a titanium (Ti) surface layer alloyed by zirconium (Zr), niobium (Nb), and aluminum (Al) under the impact of compression plasma flows on an Nb–Ti–Zr–Al/Ti substrate coating system were investigated. X-ray diffraction analysis, scanning electron microscopy, energy-dispersive microanalysis, microhardness measurements, and tribological tests were used as investigation techniques. The findings showed that the plasma impact resulted in dissolution of the coating and formation of a Ti surface layer with a thickness of ~ 10 μm alloyed by Zr, Nb, and Al atoms. The increase in the energy absorbed by the surface layer resulted in a decrease in the concentration of the alloyed elements. Solid solutions based on the α-Ti and martensite α-Ti phases were observed in the alloyed layer. Surface titanium nitride formed after the plasma impact due to the usage of nitrogen as a plasma generating gas. Alloying by plasma impact led to an increase in the microhardness and a decrease in the friction coefficient. |
