纳米摩擦学是９０年代摩擦学研究最活跃的领域之一［１］。稀土元素由于具有４ｆ电子特性，使其元素及其化合物具有许多特殊的性能［２～８］。本研究采用吸附共沉淀表面修饰法制备了烷基磷酸盐修饰的Ｌａ２（Ｃ２Ｏ４）３纳米微粒，并将其分散于润滑基础油中考察其摩擦学行为
Nano-tribology is one of the most active areas of tribological research in the 1990s [1]. Due to the 4f electronic properties of rare earth elements, their elements and their compounds have many special properties [2-8]. In this study, alkyl phosphate modified La2 (C2O4) 3 nanoparticles were prepared by adsorption co-precipitation surface modification and dispersed in lubricating base oil to investigate the tribological behavior
