| 摘 要： | 利用固相反应法在真空石英管中制备出了具有无机类纳米片层状结构的WSe2。对所合成的纳米材料分别用扫描电子显微镜、透射电子显微镜进行表征并对生长机理进行了分析;将其以不同质量分数分散到基础油HVI750中,利用摩擦磨损试验机及非接触式光学轮廓仪初步研究了其摩擦学性能,并通过测量摩擦副接触表面间油膜电阻监测其摩擦表面的成膜情况。结果显示生成物中含有两种尺度的六边形WSe2纳米形貌;含2%(质量比)WSe2润滑油添加剂的油样相对于基础油HVI750在载荷2 N,转速400 r/min,摩擦半径7 mm,实验时间30 min条件下的减摩(摩擦系数0.083)耐磨(比磨损率9.008×10-6mm3.m-1.N-1)性能较佳,平均油膜电阻为95.28 kΩ。因此得出WSe2做润滑油添加剂具有较好减摩抗磨性能,摩擦机理被提出。
