Popis:	Atomic physics methods, atomic force microscopy, and testing of microhardness, wear resistance, and friction coefficient were used to investigate Ti41-V41-Al18 samples implanted with iron (60 kV) and zirconium (40 kV) ions, and then exposed to a high-current electron beam with energy fluxes of 2.7 and 5.5 J/cm2. The maximum concentration of iron ions is 16.5 at.% at a depth of 85 nm and that of zirconium ions 0.85 at.% at 56 nm. After double implantation, the friction coefficient decreases and the wear resistance increases. After implantation and high-current electron beam treatment, the depth of the hardened layer and the wear resistance increase.
