摘　　要：制备4种不同组分的复合磺酸钙基润滑脂,采用四球摩擦磨损机和SVR高频线性振动试验机,考察12-羟基硬脂酸钙、硼酸钙对复合磺酸钙基润滑脂摩擦磨损性能的影响,采用XPS分析钢球磨斑表面主要元素的化学状态。结果表明,复合磺酸钙基润滑脂优良的极压性主要来源于层状结构的方解型碳酸钙沉积膜,而不是FeS、CaS、Fe3C、CaC2反应膜;抗磨性归功于硼酸钙、12-羟基硬脂酸钙所形成的极性吸附膜。The four kinds of calcium of sulfonate complex greases were prepared. The influence of calcium 12-hydroxystearate and calcium tetraborate on friction and wear behavior of the prepared calcium sulfonate complex greases was evaluated by four-ball tester and SRV friction and wear testing machine, and the chemical states of typical elements on the wear scar of steel ball were analyzed by means of the XPS. It is shown that excellent extreme pressure property of calcium sulfonate complex grease is mainly from layered calcium carbonate in the form of calcite rather than action of the boundary layer of FeS, CaS, Fe3C and CaC2. Antiwear characteristic could be attributed to the polar adsorption film formed by calcium 12- bydroxystearate and calcium tetraborate.
