摘要

Abstract—

The chemical composition, surface morphology, and electrochemical properties of Ti–Al–V alloys in the initial state and after irradiation with О+ ions and alternating irradiation with О+ and N+ ions differing in the irradiation dose of N+ ions are studied. Under irradiation with О+ ions, the active oxidation of Ti atoms is shown to occur, which is accompanied by the formation of titanium oxides and hydroxides. In the course of subsequent irradiation with N+ ions, the accumulation of nitrogen and formation of titanium nitride TiN are found to occur to lower concentrations as compared to those observed without the preliminary irradiation with О+ ions. It is assumed that this is due to the higher chemical activity of oxygen with respect to titanium atoms, as compared to that of nitrogen.
