摘要：

The structure, phase, element composition, and surface morphology of Ti/steel systems subjected to the treatment of high-intensity pulsed ion beams were investigated in this work. Numerical simulation, scanning electron microscopy, energy dispersion x-ray microanalysis, and x-ray diffraction analysis were used as investigation techniques. Ion beam impact with a Ti/steel system was accompanied with surface layer ablation, melting, mixing, and generation of shock waves. The findings showed that mixing efficiency was dependent on the power of the ion beam and the number of pulses. The synthesis of the mixed layer with a thickness of similar to 2 mu m containing FeTi and Fe2Ti phases was observed just after one pulse of treatment, with the energy absorbed by the surface layer of 3.1 J/cm(2). Ti concentration in the surface layer, as well as intermetallide volume fraction, was dependent on the number of pulses. Growth of the pulse number led to more uniform distribution of Ti in the mixed layer. The synthesized surface layer possessed increased microhardness.
