摘要
选择了吐温(Tween)-60、司本(Span)-20、司本(Span)-80和聚醚表面活性剂,配制了纳米稀土(RE)和铁粒子的复合润滑油。采用透射电子显微镜(TEM)观察、测定了纳米稀土、铁粒子形貌和粒径。采用磨损试验机测试了含纳米稀土、铁复合粒子润滑油的摩擦学性能。结果表明:纳米稀土与纳米铁粒子比例为1∶1,总浓度为0.6%时该润滑油具有最佳的抗磨、减摩性能。并探讨了其抗磨、减摩机制。
Tween-60,Span-20,Span-80 and Polyether surfactants were selected,lubricating oils containing nano-rare earths and Fe particles were prepared.The morphology and size of the rare earths and Fe nanoparticles were examined by transmission electron microscopy(TEM).Tribological properties were carried out in tribotester.The research results show that lubricating oil has optimum properties of friction-reduction and wear resistanc when proportion of nano-RE and nano-Fe is 1∶1,and the total content is 0.6%.The anti-wearing and friction reducing mechanism of lubricating oils was discussed as well.
