| 摘 要： | 利用四球摩擦磨损试验机对硫化锑纳米棒束作为液体石蜡添加剂的摩擦学性能进行了研究. 结合硫化锑纳米颗粒的性能, 对比分析两者作为添加剂润滑下摩擦系数、磨斑直径、钢球磨损表面形貌的变化规律, 并得到以下结论: 两种材料均能在一定程度上改善基础油的减摩抗磨性能, 在低载荷时硫化锑纳米棒束的减摩抗磨性能明显优于纳米颗粒, 较高载荷时, 两者的减摩抗磨性能相当; 就承载能力而言, 纳米颗粒的性能明显优于纳米棒束; 低载时纳米棒束的“微滚珠”效应是其优异摩擦学性能的主要原因.

| Abstract: | The tribological properties of Sb2S3 nano-bundles as an additive in liquid paraffin were evaluated on a four-ball tester,thereafter the performance of Sb2S3 nano-bundles was compared with that of Sb2S3 nano-particles.The comparative analyses of friction coefficients,wear scar diameters and morphology of worn surfaces show that Sb2S3 nano-bundles and nano-particles can both improve tribological properties of base oil,Sb2S3 nano-bundles exhibit better friction reduction and anti-wear properties than Sb2S3 nan... |
