| 目的 研究金属Cr层对Cr/Cr2N纳米多层涂层结构和性能的影响，为多层硬质涂层在海洋等腐蚀性介质中的应用提供理论基础。方法 采用多弧离子镀技术制备一系列不同金属Cr层厚度的Cr/Cr2N纳米多层涂层，采用XRD、SEM、纳米压痕及划痕仪测试了多层涂层的结构、微观形貌和机械性能。采用电化学工作站评价了Cr/Cr2N纳米多层涂层在海水环境下的电化学行为，并采用摩擦实验机测试了涂层在海水环境下的摩擦学性能。结果 Cr层对Cr/Cr2N纳米多层涂层的结构产生了一定的影响。不同Cr层厚度的Cr/Cr2N纳米多层涂层在海水环境下的磨损率差别不大，均约为1.2×10−6 mm3/(N•m)，具有良好的耐磨损性能。Cr层厚度约为21 nm的Cr/Cr2N纳米多层涂层在海水环境下具有较高的阻抗值，呈现出较高的耐腐蚀性能。结论 一定厚度的金属层（如Cr层厚度约为21 nm）和界面是多层涂层呈现较高耐腐蚀性能的关键。Cr/Cr2N纳米多层涂层在海水环境下良好的耐腐蚀和耐磨损性能，使其可应用于海洋等腐蚀性介质中，并发挥良好的表面防护作用。 |

| The work aims to study influences of Cr layers on structures and properties of Cr/Cr2N nano-multilayer coatings, so as to provide theoretical basis for applications of hard coatings in corrosive mediums including seawater. A series of Cr/Cr2N nano-multilayer coatings with different depths of Cr layers were prepared relying on multi-arc ion plating technology. Structures, morphologies and mechanical properties of multilayer coatings were tested with XRD, SEM, nano-indentation and scratch tester, respectively. Electrochemical behaviors of the Cr/Cr2N nano-multilayer coatings in seawater were evaluated with electrochemical workstation. Furthermore, tribological properties of the as-deposited coatings were tested with a tribo-meter. Cr layer had certain effect on structures of the Cr/Cr2N nano-multilayer coatings. Wear rates of the different depths of coatings in seawater were similar, which were approximately 1.2×10−6 mm3/(N•m). The low wear rate indicated excellent wear resistance of the as-deposited coatings. The Cr/Cr2N nano-multilayer coatings with nearly 21 nm thick Cr layer exhibited excellent corrosion resistance with the high impedance in seawater. Metal layer of proper thickness including Cr layer and the interface is crucial to high corrosion resistance of the Cr/Cr2N nano-multilayer coatings. The excellent corrosion and wear resistance of Cr/Cr2N nano-multilayer coatings made them good protective materials in corrosive mediums including seawater. |
