磺化石墨烯提升受电弓炭滑板材料在常规和潮湿条件下的抗磨性
Sulfonated graphene improves the wear resistance of pantograph carbon slider materials under normal and wet conditions
摘要
Abstract
A novel pantograph carbon slider (PCS-1) was designed and prepared via mold pressing, hot extrusion and sintering using sulfonated graphene (SG) as additive. The results show that PCS-1 demonstrates an obvious enhanced mechanical strength and wear performances than that of carbon slider in the absence of SG (PCS-0). For example, the current-carrying wear test indicates that the flexural strength of PCS-1 is 41.8％ higher than that PCS-0 counterparts. The wear rate of PCS-1 reduces 51.0％ and 50.0％ in the wet and normal conditions, respectively. Moreover, the presence of SG, as reflected in scanning electron microscopy, polarizing mi-croscope and white light interferometer, can markedly decrease the number of random cracks, increase the compactness of fracture surface and inhibit the electro-erosion of the slider materials, thus improving the mechanical strength and wear resistance signific-antly.关键词
