【Abstract】 The effect of silicon was studied on the wear resistance of Al\|Si alloy and its composite, γ Al\-2O\-\{3f\}/Al Si. The results show that the wear resistance of Al\|Si alloy increases with the increase of silicon content, while silicon content exerts little effect on that of the composite; after modification with silicon, there is a little improvement in the wear resistance of γ Al\-2O\-\{3f\}/Al 12Si, but Al\|12Si alloy has a lower wear resistance; the wear resistance of Al\|17Si alloy is close to that of its composite γ Al\-2O\-\{3f\}/Al 17Si.更多还原
