摘要：

研究在润滑油中添加石墨烯提高其极压抗磨性能。应用油酸、硬脂酸等对石墨烯进行表面改性，通过扫描电镜、拉曼光谱仪分析改性石墨烯的形貌结构，分光光度计观察改性石墨烯在润滑油中的悬浮稳定性，采用摩擦磨损试验机测试加入改性石墨烯的润滑油的摩擦学性能。结果表明，石墨烯经表面改性后形貌发生了变化，提高了在润滑油中的悬浮稳定性。润滑油添加质量分数为0.075％的改性石墨烯，耐磨性和承载能力有很大提高。

Abstract:

This paper studied on adding graphene in lubricating oil add to improve its extreme pressure antiwear performance. The surface of graphene was modified by oleic acid and stearic acid. The morphology of modified graphene was analyzed by scanning electron microscopy and Raman spectroscopy. The stability of modified graphene in suspension was observed by spectrophotometer. Friction and wear testing machine was used to test the tribological properties of lubricating oil with modified graphene. The results showed that the morphology of graphene changed after surface modification, which improved the suspension stability in lubricating oil. A modified graphene with a mass fraction of 0.075% was added to the lubricant, whose wear resistance and loadbearing capacity were greatly improved.

Key words: tribology, lubricating oil, graphene, surface modification
