通过ＳｑｕｅｅｚｅＣａｓｔｉｎｇ工艺制备了钛酸钾（Ｋ２Ｏ·６ＴｉＯ２）晶须增强锌铝合金（ＺＡ２７）复合材料，分析了Ｋ２Ｏ·６ＴｉＯ２（ｗ）／ＺＡ２７合金复合材料的微观组织特性，研究该复合材料及基体合金室温及高温（～１５０℃）摩擦磨损性能．实验结果表明：在边界润滑条件下，复合材料的高温耐磨性能比基体合金有显著提高；利用ＳＥＭ５０５扫描电镜对两种材料的磨损表面微观形貌进行了观察，并讨论了高温磨损失效机制． The microstructure characteristics of K2O · 6TiO2 (w) / ZA27 alloy composites were investigated by means of SqueezeCasting process. The effects of K2O · 6TiO2 whiskers on the microstructure and mechanical properties of ZA27 alloy composites were studied. The composite and matrix alloy at room temperature and high temperature (~ 150 ℃) friction and wear properties. The experimental results show that under the condition of boundary lubrication, the wear resistance of the composite at high temperature is significantly higher than that of the matrix alloy. The microscopic morphology of the wear surface of the two materials is observed by SEM505 scanning electron microscope, and the effects of high temperature wear failure mechanism.
