利用液相脉冲放电涂层技术(EDC)在45#钢基体上制备出TiCN金属陶瓷涂层，对涂层的成分、表界面形貌及显微组织进行分析和表征。研究涂层的常温滑动摩擦磨损行为，并与物理气相沉积(PVD)法所制备的TiN涂层进行对比。结果表明：所制备的TiCN涂层厚度约为15μm，主要由TiC 0.3 N 0.7相组成。在较小的载荷下，经由两种方法所制备的涂层的磨损量相差不大，但当载荷增加至30 N时，PVD方法所制备的TiN涂层出现严重的涂层剥落，而采用EDC方法所制备的TiCN涂层具有更好的耐磨擦磨损性能，磨粒磨损与剥层磨损是重载下涂层摩擦磨损的主要机制。

Titanium carbonitride (TiCN) coating was prepared on 45# carbon steel by electrical discharge coating (EDC), and the compositions, morphology and microstructure of the coating were studied. In addition, its friction and wear behaviors relative to the physical vapor deposition (PVD) TiN coating were investigated. The results show that the TiCN coating features a thickness of 15μm with a primary phase of TiC 0.3 N 0.7 . The wear rates of the two coatings have no clear distinction at low applied loads. However, severe abrasive wear appears in the PVD TiN coating when the applied load exceeds 30 N, while the TiCN coating features better wear resistance. The abrasive wear with coating peelings is found to be the predominant wear mechanism at high applied loads.
