摘　　要：本文制备了Al_2O_3/SiO_2混杂颗粒填充的环氧树脂基材料,并通过磨损试验机和扫描电子显微镜研究了材料的摩擦磨损性能和磨损机理。结果表明:采用KH570表面改性的纳米Al_2O_3/SiO_2混杂颗粒填充分散良好;Al_2O_3/SiO_2质量分数为10%时,环氧树脂材料的磨损率为2.71×10^(-6)mm^3/(N·m),摩擦系数为0.25,显著提高了环氧树脂的抗磨损性能,且硬度提高到了85D;环氧树脂基复合材料磨损机理以粘着磨损和磨粒磨损为主。In this paper,the epoxy resin based materials filled with Al2O3/SiO2 hybrid particles were prepared,and the friction and wear properties and wear mechanism of the materials were studied by wear tester and scanning electron microscope. The results show that the nano Al2O3/SiO2 hybrid particles with KH570 surface modification are well filled and dispersed. When the mass fraction of Al2O3/SiO2 is 10%,the wear rate of epoxy resin is 2. 71 × 10^-6 mm^3/（ N · m） and the friction coefficient is 0. 25,which significantly improves the wear performance of the epoxy resin,and the hardness is increased to 85 D. The wear mechanism of epoxy resin-based composites is mainly adhesive wear and abrasive wear.
