Abstract The tribological performance of new epoxy resin (RE) coatings on mild steel AISI 1015 substrate has been studied under pin-on-disk configuration against AISI 316L stainless steel. Both single layer and double layer coatings were obtained by spin coating and curing. A single layer coating of RE modified by a dispersion of graphene (G) in the aprotic ionic liquid 1-octyl-3-methylimidazolium tetrafluoroborate, RE+9 wt.%([OMIM]BF4+0.1 wt.%G), prevents wear and reduces the coefficient of friction in a 60% with respect to RE. When the fluorine-free protic ionic liquid bis(2-hydroxyethyl)ammonium oleate (DO) is used, a double layer coating is necessary to achieve wear prevention and friction reduction up to 70% for RE+9 wt.%DO, and up to 50% for RE+9 wt.%(DO+0.1 wt.%G).

离子液体和石墨烯改性环氧涂层的摩擦学表征

摘要 针对 AISI 316L 不锈钢，在针盘配置下研究了新型环氧树脂 (RE) 涂层在低碳钢 AISI 1015 基材上的摩擦学性能。单层和双层涂层均通过旋涂和固化获得。通过石墨烯 (G) 在非质子离子液体 1-octyl-3-methylimidazolium 四氟硼酸盐中的分散体改性的 RE 单层涂层，RE+9 wt.%([OMIM]BF4+0.1 wt.%G)，防止磨损并将摩擦系数降低 60%（相对于 RE）。当使用无氟质子离子液体双（2-羟乙基）油酸铵 (DO) 时，需要双层涂层以实现 RE+9 wt.%DO 和高达 70% 的耐磨和减摩效果RE+9 wt.% (DO+0.1 wt.%G) 至 50%。
