Sliding dynamics on ultrafine grained Al–6 wt % Mg made by equal channel single pressing

The effect of ECAP pass number on wear, microhardness and tribological dynamic behavior of UFG Al– 6 wt % Mg alloy has been studied. The UFG Al–6 wt % Mg samples demonstrated higher wear resistance after 4 and 8 ECAP passes as compared to as-received alloys state. The dynamics of sliding and loudness level generated in sliding showed moderate increase of vibrations and noise on ECAP UFG samples.
