| 目的 讨论海水环境下不同基体材料对Cr/CrN交替的多层复合涂层磨蚀性能的影响，为海水环境下耐磨蚀材料基体的选择和应用提供参考。方法 采用多弧离子镀技术在316L不锈钢和TC4钛合金基体上沉积Cr/CrN多层复合涂层，通过XRD、SEM等技术对涂层材料的微观结构进行表征，通过硬度测试、结合力测试、电化学分析、摩擦磨损试验等技术对涂层材料的力学性能、电化学性能以及摩擦学性能进行分析，比较不同基体对Cr/CrN多层涂层在海水环境中磨蚀性能的影响。结果 以TC4钛合金为基体的Cr/CrN多层涂层的硬度为1727.2HV0.3，虽略小于以316L不锈钢为基体的涂层硬度（2241.5HV0.3），但其在膜-基结合力、海水环境下电化学性能和摩擦学性能等方面均优于以316L不锈钢为基体的涂层。结合力测试中，以TC4为基体的多层涂层初始裂纹出现在31 N，扩展裂纹出现在42 N，大于316L基体涂层的22 N和35 N。电化学测试中TC4基体涂层的腐蚀电位为?0.20 V，大于316L基体涂层的腐蚀电位（?0.21 V）。海水环境下TC4基体涂层的平均摩擦系数和磨损率分别为0.35和2.9950×10?5 mm3/(N?m)，均小于316 L基体涂层的平均摩擦系数（0.36）和磨损率（4.9895×10?5 mm3/(N?m)）。结论 TC4钛合金更适合作为海水环境用Cr/CrN多层涂层耐磨蚀材料的基体材料。 |

| The work aims to discuss the effects of different substrate materials on the tribocorrosion performance of Cr/CrN alternating multilayer composite coatings in seawater, so as to provide references for the selection and application of an-ti-tribocorrosion material substrate in seawater. Cr/CrN multilayer composite coating was deposited on 316L stainless steel and TC4 titanium alloy substrate by multi-arc ion plating technique. The microstructure of coating materials was characterized by XRD and SEM and the mechanical properties, electrochemical properties and tribological properties of coating materials were analyzed by hardness test, adhesion test, electrochemical analysis, friction and wear test to compare the effects of different substrates on tribocorrosion performance of Cr/CrN multilayer coating in seawater. The hardness of the Cr/CrN multilayer coating with TC4 titanium alloy as the substrate was 1727.2HV0.3, although slightly lower than the hardness of the coating with 316L stainless steel as the substrate (2241.5HV0.3), but it was superior to the coating properties of 316L stainless steel in the membrane-base binding force, the electrochemical performance and the tribological properties of the seawater environment. The initial cracks appeared at 31 N and the extended cracks appeared at 42 N of multilayer coating with TC4 as substrate in the adhesion test, which was larger than 22 N and 35 N of 316L substrate coating. The corrosion potential of TC4 substrate coating was ?0.20 V in electrochemical test, and the corrosion potential of the 316L substrate coating was ?0.21 V. The average friction coefficient and wear rate of the TC4 substrate coating in seawater were 0.35 and 2.9950×10?5 mm3/(N?m), respectively, which were less than average friction coefficient of 0.36 and wear rate of 4.9895×10?5 mm3/(N?m) of 316L substrate coating. TC4 titanium alloy is more suitable to be used as the substrate material of Cr/CrN multilayer coating anti-tribological materials in seawater. |
