中文摘要:
      采用硅烷偶联剂KH-570作为表面分散剂,利用机械球磨法制备了不同粒径的纳米锑颗粒,将其分散到900SN基础油中,在CFT-1型材料性能测试仪上进行往复式摩擦实验,考察其作为润滑油添加剂的摩擦学性能。采用SEM和EDS分析了45钢钢盘磨损表面的形貌和化学成分。结果表明:纳米锑颗粒以微观填充与黏着的机制对磨损表面起到修复作用。随着纳米锑颗粒粒径的减小和摩擦载荷的增大,试验润滑油的减摩、抗磨效果越明显。其中,含粒径为40nm的锑颗粒润滑油在高载荷下表现出优异的减摩与抗磨性能。
Effect of Particle Size of Antimony Nanoparticles on Tribological Properties of Lubricant Oil

英文摘要:
      The antimony nanoparticles with different particle sizes were prepared by mechanical ball milling method while the particles surface was modified by silane coupling agent KH-570. The tribological properties of experimental lubricating oil, which are 900SN and others lubricating oils containing antimony nanoparticles with various particle size,were studied by reciprocating friction experiment in CFT-1 material performance tester. The worn surface morphology and chemical composition of 45 steel were analyzed by SEM and EDS. The results show that antimony nanoparticles play a role in repairing effect for worn surface basing on micro-filling and adhesion mechanism. With decreasing of particle size of antimony nanoparticles and increasing of frication load, the antifriction and antiwear properties of experimental lubricating oils increase. The experimental lubricating oil containing antimony nanoparticles with 40 nm of particle size has good antifriction and antiwear properties under higher friction load.
