Abstract

The tribological behavior of nanocrystalline Fe₈₈Si₁₂ alloy in vacuum environment has been investigated compared with coarse grained counterpart. The results demonstrated that the friction coefficient of the Fe₈₈Si₁₂ alloy reduced with the decrease of both grain size and oxygen partial pressure. The wear resistance of the Fe₈₈Si₁₂ alloy improved more effective in vacuum than in air as the grain size decreased. As the hardness and oxidation activity of the Fe₈₈Si₁₂ alloy decreased, the wear mechanism changed from adhesion and oxidation to plastic deformation and adhesion when the grain size and oxygen partial pressure decreased.
