摘　　要：以化学还原法从电镀铜废液中回收的纳米铜粉为固体润滑油添加剂,在四球式摩擦磨损试验机上研究纳米铜粉的加入量对润滑油摩擦学性能的影响。采用SEM、EDAX等分析磨斑表面,初步探讨纳米铜粉抗磨减摩机制。结果表明:纳米铜粉的添加显著提高基础油的抗磨减摩性能,当纳米铜粉加入量为0.3%(质量分数)时,其摩擦因数和磨斑直径分别比基础油减小33.4%和19%。含纳米铜粉润滑油在高载荷下具有更好的抗磨减摩性能。纳米铜粉在摩擦过程中抗磨减摩机制主要为填充作用和沉积自修复膜作用机制。The copper nanoparticles prepared from electroplating effluent by chemical reduction method were used as solid lubricant addictive.The impact of copper nanoparticles on the tribological properties of lubricant was studied by four-ball tribotester.The worn surfaces were analysed by SEM and EDAS.Results show that the tribological property of the base oil is improved by copper nanoparticles.When the mass content of copper nanoparticles is 0.3%,the friction coefficient and wear scar diameter are decreased by 33.4% and 19% respectively.The friction reducing and antiwear properties of the lubricant with copper nanoparticles are more excellent under high-load.In the friction process,copper nanoparticles mainly act as filler and deposit self-repairing membrane.
