纳米颗粒的抗磨作用及作为磨损修复添加剂的应用研究
刘维民,周静芳

摘要:
用化学修饰法合成了在润滑油中具有良好分散性能的二烷基二硫代磷酸（DDP）表面修饰铜Cu纳米颗粒（简称Cu-DDP)和DDP表面修饰LaF3纳米颗粒（简称LaF3-DDP)，考察了它们作为润滑油添加剂的减摩、抗磨作用和承载能力，研究了它们的抗磨损和润滑机理。研究发现，Cu-DDP和LaF3-DDP纳米微粒具有良好的抗磨损性能，优异的极压性能，可以显著地提高基础油的失效负荷，尤其在高载荷条件下，比商品添加剂二烷基二硫代磷酸锌（ZDDP）具有更好的润滑性能。SEM和XPS分析表明，纳米Cu-DDP和LaF3-DDP作为润滑油添加剂主要形成和由Cu或LaF3的沉积膜及硫、磷与金属反应生成的摩擦化学反应膜共同组成的复合边界润滑表面膜从而具有抗磨损和抗极压性能。

Antiwear Properties of Nanoparticles and Application study of Nanoparticles as Additives in the wear-repairing agent
Liu Weimin Xue Qunji Zhou Jingfang Zhang Zhijun
Abstract:
Cu-DDP and LaF3-DDP of good dispersity in lubricating oil were sythetized via chemical modification. The antiwear, Triction-reducing and load-bearing properties of Cu-DDP and LaF3-DDP as lubricating additives were carefully examined. This paper also studied the antiwear and lubrication mechnism of nanoparticles. The resutts showed that the nanoparticles were better lubricants than commercial additive ZDDP under high load.
