以聚α-烯烃(PAO40)为基础油、以复合锂皂为稠化剂制备了复合锂基润滑脂,采用MFT-R4000高速往复摩擦磨损试验机,考察了二丁基二硫代氨基甲酸钼(T351)、氨基硫代酯(T323)等添加剂在钢-钢摩擦副下的摩擦磨损性能.利用扫描电子显微镜(SEM)和能谱分析仪(EDS)观察并分析了钢块磨痕表面形貌和磨斑表面主要化学元素组成.在此基础上,通过多种添加剂复配自制的风电轴承润滑脂的摩擦学性能优于国外某著名品牌的风电轴承润滑脂.%A kind of complex lithium-based grease for wind power was synthesized using poly-αo-lefin(PAO40 )as base oil and complex lithium soap as thickener. The effects of additives including dib-utyl dithiocarbamate(T351 )and amino-sulfide(T323 )on the friction reduction and anti-wear abilities for steel/steel pairs were investigated by MFT-R4000 high-speed reciprocating friction and wear test-er. The morphologies and typical chemical composition of the worn surfaces were characterized by scanning electron microscopy (SEM )and energy-dispersive X-ray spectroscopy (EDS ). The results showed that the prepared wind power grease exhibits preferable tribological properties compared with the imported wind power grease.
