摘　　要：通过氧化还原反应与管式炉的真空加热,合成了无机类富勒烯结构二硫化钼纳米颗粒,并利用扫描电子显微镜、透射电子显微镜等手段对所合成的二硫化钼纳米颗粒进行了表征。采用粉末冶金技术,制备了含无机类富勒烯二硫化钼的自润滑材料,并利用UMT摩擦磨损试验机,研究了所制备的复合材料的摩擦磨损性能。研究结果表明,加入适量的二硫化钼纳米颗粒之后,复合材料的摩擦系数明显降低,抗磨损性能提高。The inorganic fullerene-like molybdenum disulfide nanoparticles were synthesized by redox reaction and vacuum heating in a tube furnace,and the synthesized molybdenum disulfide nanoparticles were characterized by scanning electron microscopy and transmission electron microscopy. Using powder metallurgy technology,a self-lubricating material containing inorganic fullerene-like molybdenum disulfide was prepared,and the friction and wear properties of the prepared composite material were studied by using a UMT friction and wear tester. The results showed that the friction coefficient of the composite material was significantly reduced after adding appropriate amount of molybdenum disulfide nanoparticles,and the anti-wear properties were improved.
