摘　　要：采用搅拌铸造法制备了纳米SiC颗粒增强AZ91D镁基复合材料,并对该复合材料的显微组织、硬度及摩擦磨损行为进行分析。结果表明,纳米SiC颗粒的加入能细化组织;随着纳米SiC颗粒含量的增加,该复合材料的硬度和摩擦磨损性先增大后减小。SiC nanoparticles reinforced AZ91D composite were prepared by casting with stirring. The microstructure, hardness, friction and wear behavior of the composite were analyzed. The results indicate that the addition of SiC nanoparticles can refine the microstrucaxre. With the increase of SiC nanoparticles content, the hardness, friction and wear behavior of the composite increase first and then decrease.
