| 目的 研究Mo 含量对CrN 薄膜硬度、结合力和耐腐蚀性能的影响。方法 用多弧离子镀技术，在4Cr13 钢表面沉积CrN，并掺杂不同量的Mo 原子。通过显微硬度计、附着力划痕仪、电化学测量仪和能谱仪分别检测薄膜的硬度、结合力、电化学腐蚀性能和薄膜的元素含量。结果 当Mo 的原子数分数为0.15%、4.23%、5.15%、7.09%、14.26%、21.12%、31.08%时，硬度值分别为2141.1HV、2416.0HV、2416.0HV、2962.3HV、2580.4HV、2710.5HV、2441.8HV，结合力分别为45、47、52、57、38、37、34 N；在3.5% NaCl 溶液中，它们的相对腐蚀速率分别是Mo（5.15%）的6.53、4.12、1、2.22、8.72、.2.42、2.44 倍；在1 mol/L NaOH 溶液中，它们的相对腐蚀速率分别是Mo（14.26%）的6.74、5.29、1.49、2.82、2.57、1、7.25 倍；在1 mol/L H2SO4 溶液中，它们的相对腐蚀速率分别是Mo（14.26%）的9.20、4.10、10.31、9.25、1、3.29、7.46 倍。结论 当Mo 的原子数分数为7.09% 时，结合力最大为57 N，显微硬度达到最大值，为2962.3HV；当Mo 的原子数分数为14.26%时，在H2SO4 溶液和NaOH 溶液中的耐蚀性能最好；当Mo 的原子数分数为5.15%时，在NaCl 溶液中的耐蚀性能最好。复合薄膜腐蚀机理主要是局部腐蚀中的小孔腐蚀，另外也会发生缝隙腐蚀和电偶腐蚀。 |

| The work aims to study influence of different Mo contents on hardness, binding force and corrosion resistance of CrN films. CrMoN films were deposited with different amounts of Mo atom on the surface of 4Cr13 stainless steel by multi-arc ion plating (MAIP). The hardness, binding force, electrochemical corrosion resistance and element content of CrMoN films were respectively investigated by microhardness tester, adhesion scratch tester, electrochemical measuring instrument and energy disperse spectroscopy. The results showed that when the Mo atomicity fractions of CrMoN achieved 0.15%, 4.23%, 5.15%, 7.09%, 14.26%, 21.12% and 31.08%, the hardness values were respectively 2141.1HV, 2416.0HV, 2416.0HV, 2962.3HV, 2580.4HV, 2710.5HV and 2441.8HV while the binding forces were respectively 45, 47, 52, 57, 38, 37, 34 N. In 3.5% NaCl solution, the relative corrosion rate was respectively 6.53, 4.12, 1, 2.22, 8.72, 2.42 and 2.44 times of that Mo (5.15%). In 1 mol/L NaOH solution, the relative corrosion rate was respectively 6.74, 5.29, 1.49, 2.82, 2.57, 1, 7.25 times of that of Mo (14.26%). In 1 mol/L H2SO4 solution, the relative corrosion rate was respectively 9.20, 4.10, 10.31, 9.25, 1, 3.29 and 7.46 times of that of Mo (14.26%). The binding force can be up to 57 N and microhardness reaches the maximum—2962.3HV when the Mo atomicity fraction reaches 7.09%. Corrosion resistance is best in H2SO4 solution and NaOH solution when the Mo atomicity fraction reaches 14.26%. Corrosion resistance is best in NaCl solution when the Mo atomicity fraction reaches 5.15%. Corrosion mechanism of composite films is mainly pitting corrosion, and crevice and galvanic corrosion are present as well. |
