The paper deals with the study of the effect of surface and bulk modification of the structure of titanium VT1-0 on its tribological behavior. The optimal conditions of the treatment of titanium by an electron beam are determined: the duration of the electronbeam pulse is 50 μs, the number of pulses is three, and the electron beam energy density is 25 J/cm 2 for coarse-grained and 20 J/cm 2 for ultra-fine-grained titanium. These conditions favor a several-fold reduction of the material wear during friction. The friction surface morphology is examined and island secondary structures and a grooved structure with signs of seizure are found. It is supposed that friction results in the self-organization of stable secondary structures which yield a multifold increase in the wear rate of commercially pure titanium VT1-0.
