摘要:
为提高海洋机械系统关键摩擦零部件的摩擦学性能，分别用多弧离子镀制备的TiN、TiCN和CrN涂层进行其表面防护。通过扫描电子显微镜（SEM）、能谱仪（EDS）和X射线衍射仪（XRD）表征涂层的结构，用纳米压痕和划痕仪测试其硬度和结合力，并用UMT3往复式摩擦磨损试验机测试涂层的摩擦磨损性能。结果表明，在海水环境中CrN涂层具有最低的摩擦因数。TiN和TiCN涂层已被磨穿，而CrN涂层在海水中最大磨痕深度为1.5 μm左右，表明CrN在海水环境中具有良好的耐磨性。CrN涂层在海水中涂层的磨损率小于在蒸馏水中，说明海水的腐蚀作用在磨损过程中不明显，而海水环境良好的润滑性能起了主导作用，导致磨损率较低，这表明CrN涂层在海水环境中主要的磨损机理为机械磨损。

Abstract:
To improve the tribological performance of sea frictional components, TiN, TiCN and CrN coatings, were used for surface protection of the components. The coatings were prepared by arc ion plating. Scanning electron microscopy (SEM), energy dispersive Xray analysis (EDS) and Xray diffraction (XRD) were used to characterize their structure. Hardness and adhesion force were tested by nanoindentation and scratch tester, respectively. The friction and wear properties of coatings were investigated by ballondisk tribometer. The results show that the friction coefficients of CrN coatings in seawater are lower than others. The TiN and TiCN coatings are worn out. The depth of wear track for CrN coating was about 1.5 μm in seawater, which indicates the better wear resistance for CrN than that of TiN and TiCN in seawater. The wear rate of the CrN coating in seawater is lower than that in water, which indicates the wearloss related to corrosion is not as much as wearloss decreased by lower friction. This means that mechanical wear dominates the wear mechanism in seawater.
