| Abstract: | The changes of specific energy consumption, material losses, friction coefficient and dynamic hardness of Ti6Al4V during corrosive wear process in 0.5 mol/L H2SO4 solution at different potentials and in air were investigated using a pendulum scratching apparatus, the hydrogen contents in scratching tracks was measured with SIMS, and the morphologies of scratching tracks were observed by SEM. The results showed that the wear process induced the hydrogen concentrating at wear subsurface, which decreased the energy consumption per unit volume of material loss and facilitated the nucleation and propagation of the surface cracks.\= |
