Abstract
The wear resistance and friction reduction of the fabric liner are important for the service life of self-lubricating spherical plain bearings. Basalt fiber was subjected to chemical modification by grafting graphene oxide onto its surface, resulting in the preparation of GO@BF. Polytetrafluoroethylene/basalt fiber and polytetrafluoroethylene/GO@BF fabric liners were prepared, and the tribological properties were investigated. The friction regions of fabric liners were characterized by scanning electron microscopy and energy-dispersive X-ray spectroscopy, and the friction and wear mechanisms were analyzed. The results show that the addition of graphene oxide can effectively improve the friction reduction and abrasion resistance of the fabric liner. During the friction process, graphene oxide and polytetrafluoroethylene transfer film form a synergistic lubrication mechanism, which effectively reduces the formation of abrasive particles on the friction surface, and improves the tribological performance of the fabric liner.
织物衬里的耐磨性和减摩性对自润滑关节轴承的使用寿命非常重要。通过在玄武岩纤维表面接枝氧化石墨烯对其进行化学改性，制备出了 GO@BF。制备了聚四氟乙烯/玄武岩纤维和聚四氟乙烯/GO@BF 织物衬里，并对其摩擦学特性进行了研究。通过扫描电子显微镜和能量色散 X 射线光谱对织物衬里的摩擦区域进行了表征，并分析了摩擦和磨损机理。结果表明，添加氧化石墨烯能有效提高织物衬里的减摩性和耐磨性。在摩擦过程中，氧化石墨烯与聚四氟乙烯转移膜形成协同润滑机制，有效减少了摩擦表面磨粒的形成，提高了织物衬垫的摩擦学性能。
