采用冷压烧结和热挤压方法制备出1.5～5 vol%SiCP(130 nm)/Al(149～75μm)复合材料,并对其抗压、硬度和滑动磨擦特性进行了研究,旨在研究引入弥散的亚微米级SiCP对SiCP/Al复合材料磨擦性能的影响.结果表明:随着SiCP(130 nm)含量的增加,其显微硬度值也增加,在SiCP(130 nm)含量为1.5 vol%和5 vol%时,SiCP(130 nm)Al复合材料显微硬度分别为28.4和33.3;复合材料的抗压强度分别是170 MPa和186 MPa;在较高载荷下,随SiCP含量增加,复合材料的耐磨性能提高,1.5 vol%和5 vol%SiCP/Al基复合材料具有优异的滑动磨损抗力,SiCP/Al基复合材料耐磨性优于挤压态QSn6.5-0.4和纯Al;磨损表面形成Al基体弥散分布着SiCP和孔隙的理想耐磨组织.
