摘　　要：利用四球摩擦磨损实验机考察了油酸铜修饰CuO纳米颗粒作为润滑油添加剂的抗磨性能,并用扫描电子显微镜(SEM)和X-射线光电子能谱(XPS)等对钢球磨损表面进行了分析。摩擦磨损试验结果表明,当添加质量分数仅为0.025%时,油酸铜修饰CuO纳米颗粒作为润滑油添加剂即能够明显提高基础油的抗磨能力。SEM及XPS分析结果表明,油酸铜修饰CuO纳米颗粒作为润滑油添加剂在摩擦过程中形成了一层富含Cu2O和Fe2O3的化学反应膜,正是这层膜的存在使得其表现出良好的抗磨性能。The antiwear ability of copper oleate capped CuO nanoparticles as additives in liquid paraffin were investigated using a four-ball wear tester. Scanning electron microscope （SEM） and X-ray photoelectron spectroscopy （XPS） were used to study the wear surface. Results indicate that the additive concentration is 0. 025% ,copper oleate capped CuO nanoparticles as additives can effectively improve the antiwear ability of the base oil. Results of SEM and XPS show that owing to the formation of the tribochemically reacted film containing Cu2O and Fe2O3 during friction process, copper oleate capped CuO nanoparticles as additives exhibit good antiwear ability.
