摘要
研究了 Si对 Al- Si合金及其复合材料 γ- Al2 O3f/ Al- Si耐磨性的影响 .结果表明 ,Al- Si合金的耐磨性随 Si含量的升高而升高 ,而 Si含量对复合材料的耐磨性影响不大 .经过硅变质处理的γ-Al2 O3f/ Al- 12 Si复合材料的耐磨性比未变质的稍好些 ,硅变质后的 Al- 12 Si基体合金的耐磨性比未变质的低 ;当 Si量为 17%时 ,Al-
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.
