Abstract This study examined the tribological properties of novel mesh tetrahedral amorphous carbon (Mesh ta-C). Subsequently, comparison was made with conventional ta-C and a-C:H coatings under base-oil lubrication via cylindrical-pin-on-disk tribo-tester. Analysis of wear track was conducted using field-emission-scanning-electron-microscope (FE-SEM), atomic-force-microscopy (AFM), and Raman-spectroscopy. The friction coefficient for Mesh ta-C and conventional ta-C revealed a similar pattern with regard to loads. The Mesh ta-C had excellent wear resistance, where the wear rates at loads of 20 N was five and 20 times lower than conventional a-C:H and ta-C, respectively. High wear resistance of Mesh ta-C characterized by inhibition of brittle micro-fracture propagation, less in abrasive particle created during friction test, and suppressing the effect of graphitization-induced wear on the contact surface.

四面体无定形碳(ta-C)涂层网状结构对基础油润滑条件下摩擦磨损性能的影响

摘要 本研究考察了新型网状四面体无定形碳 (Mesh ta-C) 的摩擦学特性。随后，通过圆柱销盘摩擦测试仪在基础油润滑下与传统的 ta-C 和 aC:H 涂层进行了比较。使用场发射扫描电子显微镜 (FE-SEM)、原子力显微镜 (AFM) 和拉曼光谱对磨损轨迹进行分析。Mesh ta-C 和传统 ta-C 的摩擦系数显示出类似的负载模式。Mesh ta-C 具有出色的耐磨性，在 20 N 载荷下的磨损率分别比传统的 aC:H 和 ta-C 低 5 倍和 20 倍。Mesh ta-C的高耐磨性，其特点是抑制脆性微裂纹扩展，摩擦试验中产生的磨粒较少，
