摘　　要：将钼粉与升华硫和硒粉的混合粉末按一定化学计量比混合,通过固相反应法成功制备出了均匀的片状纳米颗粒。分别使用X射线粉末衍射仪（XRD）、扫描电子显微镜（SEM）以及透射电子显微镜（TEM）对该纳米粉体进行结构表征和分析,发现该粉体为MoS2/MoS1.5Se0.5混合晶相,晶粒尺寸在300-600 nm,厚度约为5 nm的片状结构。将该MoS2/MoS1.5Se0.5纳米片作为润滑油添加剂添加到基础油中,使用UMT-2型摩擦磨损试验机对其摩擦学性能进行测试,并对摩擦机理进行了解释,结果表明MoS2/MoS1.5Se0.5纳米片作为润滑油添加剂具有良好的减摩抗磨性能。The plate-like nanoparticles with uniform size were synthesized by a Solid-state thermal reaction successfully between micro-sized Mo with the mixed powders of S and Se,and then studied by X-ray diffraction（XRD）,scanning electron microscopy（SEM） and transmission electron microscopy（TEM） to determine the microstructure and morphology.The result indicated that the nanoplates were composite phases of MoS2/MoS1.5Se0.5 nanoflakes with a length of 300-600 nm and thickness of 5 nm.The tribological properties of MoS2/MoS1.5Se0.5 nanoflakes were measured on UMT-2 tribo-tester and a tribological mechanism was proposed.The results show that MoS2/MoS1.5Se0.5 nanoflakes exhibit excellent properties of friction and wear as an additive of base oil.
