研究了Ｓｉ合金化Ｚｎ－Ａｌ合金组织性能及Ｎａ变质对Ｚｎ－Ａｌ－Ｓｉ合金组织性能的影响．结果表明。Ｓｉ合金化可提高Ｚｎ－Ａｌ４３型合金的耐磨性，但降低其强度和韧性；Ｎａ变质可改变合金中Ｓｉ的形态，改善合金性能．
The microstructure and properties of Si-alloyed Zn-Al alloy and Na modification were investigated. The results show. Si alloying can improve the wear resistance of Zn-Al43 alloy, but reduce its strength and toughness; Na deterioration can change the morphology of Si alloy, improve the performance of the alloy.
