The effect of ion beams with different intensity and duration on the change in the elemental composition and chemical state of the tungsten-free hard alloy (50% TiC - 50% TiNi) surface layers has been investigated. The analysis of the morphology and composition of the hard alloy surface layers after both exposure to continuous and powerful ion beams was carried out by scanning electron microscopy and X-ray photoelectron spectroscopy. It is shown that irradiation with a continuous ion beam causes additional oxidation of the hard alloy surface. It was found that the impact of the powerful ion beam leads to a decrease in metal oxides amount and the formation of titanium carbides in the intermetallic binder phase (TiNi) of the hard alloy.
