Modification of Structure and Properties of Titanium Surfaces During Formation of Silicides and Borides Initiated by High-Energy Treatment

An analysis of binary (Ti–Si, Ti–В, Si–B) and ternary (Ti–Si–B) phase states is made, their diagrams are presented, and a possibility for formation of a large number of metastable compounds is revealed. The latter are found to form as a result of application of non-equilibrium conditions in the course of material treatment with concentrated high-energy flows. Using an x-ray diffraction analysis and electron-diffraction microscopy, the phase composition of the surface layer of technical-grade titanium (VT1-0) treated by concentrated energy flows (irradiation with plasma from electrical wire explosion and high-intensity pulsed electron beam) is investigated.
