摘要

对挤压铸渗法制备的ZTA/YL302复合材料进行冲击和磨粒磨损试验。利用光学显微镜和电子显微镜观察复合材料试验前后的表面形貌。结果表明

ZTA预制件的孔隙率为40%～55%

渗透的基体为YL302合金。相比YL302合金

复合材料的耐磨性能显著提高

但是冲击韧度有所下降;复合材料在铸态（F）下的冲击韧度比T6热处理后的冲击韧度略高

铸态下的耐磨性能比T6热处理后的高。

Abstract

The impact and abrasive wear experiments of ZTA/YL302 composites prepared by squeeze infiltration were conducted. The surface morphology of the composites before and after experiment was observed by optical microscopy （OM）and scanning electron microscopy （SEM）. The results indicate that the porosity percentage of ZTA preform reaches 40%

5% with the matrix alloy YL302. Compared with that of the YL302 alloy

the wear resistance of the composite prepared is increased by three times

however

the impact toughness is decreased slightly. The impact toughness of the composites in as-cast state（F） is slightly higher than that in T6 state

and the wear resistance is better than that in T6 treated one.
