研究了碳化物衍生碳涂层表面的划痕对其摩擦学性能的影响.扫描电子显微镜形貌图证实碳化硅基底的划痕为V-型和U-型,氯化处理后得到的碳化物衍生碳涂层的表面划痕也有相似的形貌.在干摩擦和水润滑条件下,与研磨处理的碳化物衍生碳涂层相比,未研磨处理的碳化物衍生碳涂层与氮化硅陶瓷对摩时表现出更加优异的摩擦学性能.在水润滑条件下,未研磨处理的碳化物衍生碳涂层与氮化硅陶瓷对摩时的摩擦系数仅为0.05,且比经研磨处理的碳化物衍生碳涂层的摩擦系数低.主要归因于未研磨的碳化物衍生碳涂层表面的划痕产生的流体润滑作用,而经研磨处理后的碳化物衍生碳涂层上不存在这种机制.碳化物衍生碳涂层表面的划痕有利于降低碳化物衍生碳涂层在水中与氮化硅陶瓷对摩时的摩擦.
