摘 要: 将DNCu-1型表面修饰Cu纳米微粒添加到发动机润滑油中,在发动机运行一段时间以后对连杆瓦的磨损表面进行SEM、EDS和XPS分析。结果表明,表面修饰Cu纳米微粒与润滑油有良好的相容性,可以稳定均一地分散到润滑油中;Cu纳米微粒在连杆瓦表面上形成了沉积膜使得连杆瓦上的磨损部分得到了有效的修复,并与表面修饰层形成的摩擦化学反应膜产生协同作用,从而表现出了良好的修复和抗磨作用,可延长发动机的磨损部件的使用寿命。 The surface-modified Cu nanoparticles were added into lubricant oil. After the engine working a period time, the connecting rod bush of the engine was demounted and analyzed using SEM, EDS and XPS. The results show that Cu nanoparticles can disperse steadily in the lubricant oil. Cu nanoparticles possess good anti-wear and renovating property, which form sediment film in the connecting rod bush surface, and the abrasion surface is well repaired, the useful life of the connecting rod bush is prolonged.
