| Abstract | A 150 mu m thick SiC coating was ground to form V-shaped and U-shaped grooves with a 10 µm depth, which was followed by partial chlorination to convert the coating to a carbide-derived carbon (CDC) coating. The effect of the grooves in the CDC coating on its tribological properties was investigated. The grooves were removed by further grinding for comparison. It was found that the grooved CDC coating exhibited improved tribological properties in sliding against Si3N4 in both dry and moist conditions compared with the coating without grooves. The friction coefficient of the grooved CDC coating (0.05) against Si3N4 was lower than that of the ungrooved coating under moist condition, s which can be accounted for by a hydrodynamic lubrication mechanism in the vicinity of the grooves. The grooves were also a useful surface texture to reduce the friction coefficient of the CDC coating in sliding against Si3N4 under dry conditions.; 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。 |
