通过微波-热解法制备了具有插层结构的氯氧化铁/石墨烯(FeOCl/GR)复合材料,并采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)及电子能谱(EDS)对其形貌和元素组成进行表征。利用四球摩擦磨损试验机测试FeOCl/GR润滑添加剂在聚乙二醇200(PEG-200)中的润滑性能。结果表明:FeOCl/GR对增强PEG-200的润滑性能具有协同作用,在摩擦过程中FeOCl/GR在摩擦副界面形成摩擦膜,起到减摩抗磨及提高承载力的作用。单组分FeOCl或GR在PEG-200中并未起到明显的润滑作用,然而,FeOCl/GR在PEG-200中的摩擦系数较纯PEG-200降低了37.7%。因此,基于FeOCl/GR在PEG-200中优异的润滑性能,它有望作为新型的绿色润滑添加剂应用于润滑领域。
The intercalated ferric oxychloride/graphene (FeOCl/rGO) composite was prepared by microwave-pyrolysis method,and characterized by scanning electron microscopy (SEM),X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS).The lubrication properties of the FeOCl/GR as lubricant additive in PEG-200 were tested on four-ball friction and wear tester.The results shown that the FeOCl/rGO had synergistic effect on enhancing the lubrication performance of PEG-200.During the friction process,the FeOCl/rGO formed friction film at the interface of the friction pair,which played the role of reducing wear and improving the bearing capacity.Single component FeOCl or rGO did not play positive role in PEG-200.However,the friction coefficient of FeOCl/rGO in PEG-200 was 37.7% lower than that of pure PEG-200.Therefore,based on the excellent lubrication performance of FeOCl/rGO in PEG-200,it was expected to be used as new green lubrication additive in the lubrication field.
