Findings of comparative investigations are presented for phase formation, characteristics of hardening, tribological properties, and oxidation resistance of Ti-Al intermetallic surface alloys formed by multiple alternation of deposition of an Al film (0.1-1 μm) on a Ti substrate and pulsed liquid-phase mixing of Al and Ti by intense low-energy (~15 keV) electron beams with microsecond (~3 μs) and submillisecond (100 μs) duration. It is found that microsecond synthesis is effective for formation of γ(TiAl) oxidation-resistant surface alloys. In turn, submillisecond synthesis allows one to form Ti 3Al surface alloys with enhanced wear resistance.
