摘　　要：研究了T6热处理对坩埚移动式喷射沉积A359/SiCp复合材料与树脂基摩阻材料在干摩擦状态下摩擦磨损性能的影响,结果表明:经过T6热处理,可以提高材料的硬度和耐磨性能,改善摩擦系数的稳定性,当采用530℃固溶3h水淬,随后175℃时效7h热处理工艺,A359/SiCp复合材料的磨损率为未热处理喷射沉积态时的1/10。The paper studies effects of T6 heat treatment on friction and wear of A359/SiCp composites fabricated by spray deposition, characteristic of the movable crucible, in dry sliding with polymer matrix friction materials. The results show that T6 heat treatment can increase hardness and wear resistance of composites, and achieve better stability of friction coefficient. The wear rate of composites treated at solution at 530℃ for 3 hours and water quenching, then aging for 7 hours at 175℃, is 1/10 that of composites without T6.
