含CdS纳米微粒离子液体的摩擦学行为研究.pdf

2006全国摩擦学学术会议——纪念摩擦学40周年 含CdS纳米微粒离子液体的摩擦学行为研究 张春丽，张晟卯，吴志申，张治军，张平余 (河南大学特种功能材料重点实验室，河南开封47500l，E-mail：wuzhishen@一,henu．edu．en) 摘要：合成了1-甲基-3．己基咪唑四氟硼酸盐离子液体，以所合成的离子液体勺反应介质通过有机金属化合物热分解法制 备了CdS纳米微粒。在四球摩擦磨损试验机E考察了含纳米微粒离子液体的摩擦学行为。结果表明：含纳米微粒离子液体 的减摩抗磨性能明显优于纯离子液体。CdS纳米微粒以滚动糟动的方式起到了减摩抗磨作用，同时它的存在加速了离子液 体中阴离子的分解，促进FeF2和FeF3的形成，使复合体系的减摩抗磨性能加强。 关键词：CdS纳米微粒；室温离子液体；摩擦学行为：透射电子显微镜 中图分类号：THll7．3 and BehaviorofCdS PreparationTribologyStudy Nanoparticles inRoom Ionic TemperatureLiquid ZHANG Chun-Li,ZHANGZhi—Shen,ZHANGZhi—JumZHANG Sheng-Mao，WU Ping-yu FunctionalMaterial kIbor锄)1)；Henm (Special Universit)；Kaifeng475001) Abstract：CdS were inaroom ionic nanoparticlesprepared temperature tetmfluomborate．Thebehaviorsof tetrafluomborateionic anditS tribol晒cal l-methyl-3-hexyl—imidazoliumliquid complex which CdS werestudiedonafour-ball resultsindicateflmatthe system containingnanoparticles machine,respectively．The CdS showsbetter behaviorthan ionic ionic tribological make liquidcontainingnmaoparticles pure liquid．CdS nanoparticles the exhibitbetterwear-resistmacethanthat ionic irlcreasethe system may ofanion complex ofpureliqui正It decomposition inionic existingliquid． words：CdS ionic behavior；,transmissionelectron Key nanoparticle；loomtemperatureliquid；硎)0logical micros
