摘　　要：用熔体搅拌铸造法制备了硅相增强ZA40复合材料,研究了硅含量对该复合材料的密度、硬度、金相组织和性能的影响,并通过高温高速磨损试验机测量了该复合材料的耐磨性。结果表明,随硅含量的增加,ZA40合金的耐磨性大幅提高。SiP/ZA40 composite was prepared by stir casting.The effects of Si content on density,hardness,microstructure and properties of the composite were studied.The tribological properties and corrosion behaviors of Si reinforced Zn-Al composite were tested on high temperature and high speed wear machine.The results indicate that the wear properties of ZA40 alloy gradually increase as Si content increasing.
