在湿空气中对与轴承钢接触的铝硅合金基复合材料进行了球-盘型微动磨损试验，研究了相对滑动幅度对复合材料摩擦磨损的影响。在较大的相对滑移幅度范围内，铝硅合金浸渍石墨复合材料（ALGR-MMC）的摩擦系数低于氧化铝短纤维增强复合材料（ASFR-MMC）和空心二氧化硅颗粒增强复合材料（HSPR-MMC）。AlGR-MMC的磨损率虽然高于ASFR-MMC和HSPR-MMC，但由于石墨粉末和Al-Si合金磨粒的致密膜的粘附，该复合材料几乎不对配合材料造成损坏。
Ball-against-disk type fretting wear tests for Al–Si alloy matrix composites in contact with bearing steel were conducted in wet air to investigate the effects of relative slip amplitude on friction and wear of the composites. In the larger range of relative slip amplitude, the Al–Si alloy-impregnated graphite composite (ALGR-MMC) shows lower friction coefficients than those of alumina short fiber-reinforced composite (ASFR-MMC) and hollow silica particle-reinforced composite (HSPR-MMC). Although the wear rate of the ALGR-MMC is higher than that of the ASFR-MMC and HSPR-MMC, the composite hardly causes damage to the mating material due to adhesion of compacted films of graphite powder and Al–Si alloy wear particles.
