The paper is aimed at studying the effect of a continuous ion beam of the composition (Ar + + Zr + ) with an ion energy of E ≈ 20 keV and a radiation dose of D ≈ 5 × 10 17 ions/cm 2 on the phase composition, chemical state, microhardness, wear resistance in friction against abrasive, and corrosion resistance of tungsten-free hard alloys in the TiC–TiNi system. The structure, morphology, and chemical state of the samples before and after ion-beam treatment were studied by scanning electron microscopy, scanning probe microscopy, X-ray photoelectron spectroscopy, and X-ray powder diffraction analysis. Features of the change in the physicochemical state of the tungsten-free hard alloy in the TiC–TiNi system after continuous ion-beam treatment were identified. It was experimentally determined that ion-beam treatment provides an increase in microhardness, wear resistance, and corrosion resistance of the tungsten-free hard alloy.
