摘 要: 针对恶劣提升工况下润滑失效导致的提升钢丝绳内部钢丝摩擦磨损严重的问题，开展改性氧化石墨烯润滑
油减摩特性研究. 首先，制备十八胺官能化氧化石墨烯(ODA-GO)及其水合肼还原材料(ODA-rGO)，分析其化学结
构、表面形貌、片层间距和缺陷，探究其在钢丝绳润滑油IRIS中的分散性；接着，用四球机评价改性润滑油的减摩抗
磨性能并研究其润滑机理；最后，评判ODA-GO改性油对钢丝减摩的改进效果. 结果表明：ODA通过酰胺化反应和
亲核取代反应接枝在GO表面，ODA-GO拥有高接枝密度的十八烷基链，并在IRIS中分散性较好，ODA-rGO则相反，
但在最优添加量下ODA-rGO的抗磨减摩性优于ODA-GO；改性石墨烯基材料会附着在摩擦接触表面，并填补已损
伤区域，从而减少磨损；ODA-GO改性油使钢丝间摩擦系数降低10%，疲劳磨损显著降低.

Abstract: To solve the serious tribological problem between the internal steel wires of the lifting wire ropes caused by
lubrication failure under harsh lifting conditions, the anti-friction properties of modified graphene oxide lubricants were
studied. Firstly, octadecylamine functionalized graphene oxide (ODA-GO) and its reduced material by hydrazine hydrate
(ODA-rGO) were prepared. Their chemical structure, surface morphology, interlayer spacing and defects were
investigated, and their dispersibility in a wire rope lubricant named IRIS was explored. Then, the anti-wear and friction
reduction properties of modified oils were evaluated by four-ball machine and the lubrication mechanism was analyzed.
Finally, the effect on the friction reduction between wires of ODA-GO lubricant was analyzed. The results showed that
