目的 探究钢基表面TiN基涂层在海洋环境中的耐磨蚀性能。方法 采用电弧离子镀技术，在304不锈钢和单晶硅表面分别沉积TiN、TiBN、TiBN/TiN涂层，并对3种涂层样品的表面–截面形貌、摩擦系数、在人工海水中的电化学性能和摩擦腐蚀行为进行测试。结果 形貌表征和干摩擦测试结果显示，TiBN和TiBN/TiN涂层有着比TiN柱状晶更加致密的微观结构，3种涂层的摩擦系数相差不大，比304SS的摩擦系数低。在人工海水环境中的电化学测试结果表明，TiBN/TiN涂层的耐腐蚀性能最佳，TiBN涂层次之，TiN涂层则表现出比304不锈钢基底更差的耐腐蚀特性。在发生摩擦腐蚀的过程中，3种涂层的电位(OCP)均发生了下降。结论 利用电弧离子镀技术在304不锈钢表面沉积的单层/多层TiN基涂层，在人工海水环境下，发生的摩擦会增加涂层发生腐蚀的趋势，结构致密，表面易形成钝化膜的涂层，其耐磨蚀性较好。

This work aims to investigate the coexisting antiwear and anticorrosion properties of coatings on steels applied in Marine environment. TiN, TiBN and TiBN/TiN coatings were deposited on the surface of 304 stainless steels and Si substrates by arc ion plating, respectively. The surface and cross-sectional morphology, friction coefficient, electrochemical corrosion performance and tribocorrosion behavior in artificial seawater of the samples were tested. The results showed that their dry friction coefficients are almost 0.55 compared to 0.68 for the virgin 304 SS. And TiBN and TiBN/TiN coatings had much denser microstructure than columnar crystal TiN. The results of electrochemical tests showed that TiBN/TiN coatings possess the best corrosion resistance, followed by TiBN coating, while TiN coating showed worse corrosion resistance than 304 SS. In the process of friction corrosion test, the values of open circuit potential for the three coatings decreased, indicating that the on-going friction in the artificial seawater will largely increase the tendency of corrosion of the coatings, and more uniformly dense coatings that was easily to form the surface passivated layer probably exhibit an excellent antiwear and anticorrosion feature.
