摘要: 用动电位极化、恒电位极化、Mott-Schottky测量、X射线光电子能谱（XPS）分析及扫描电子显微镜（SEM）等手段研究了氢对纳米不锈钢涂层在0.5 mol/L NaCl + 0.05 mol/L H2SO4溶液中腐蚀行为及钝化膜性能的影响。结果表明，氢与涂层表面吸附的OH-反应使OH- 吸附减少，从而延迟了钝化膜的形成；氢使钝化膜的成分发生改变，钝化膜中的OH-/O2-的比率升高，因而钝化膜的点蚀敏感性增加；同时，氢促使钝化膜的介电常数增大，空间电荷电容增大，载流子密度增加，从而降低了钝化膜的稳定性。随着充氢量的增加，钝化膜的维钝电流和载流子密度随之增加，说明钝化膜的稳定性和涂层耐蚀性能都随之降低。

Abstract：The effects of hydrogen on corrosion behavior and passive film of nano-crystalline stainless steel coat?鄄ing in 0.5 mol/L NaCl + 0.05 mol/L H2SO4 solution were investigated using electrochemical technique, X-ray photoelectron spectroscopy (XPS) analysis and scanning electron microscopy (SEM) observation. During the for?鄄mation process of passive film, the hydrogen could slow down the formation of the passive film because the exis?鄄tence of hydrogen would reduce the adsorbed OH- ions on the coating surface. XPS analysis results indicated that the OH-/O2- ratio in the passive film was changed after hydrogen charging. The susceptibility to pitting of the charged coating was enhanced because of the increment of OH-/O2- ratio in the passive film.Mott-Schottky analy?鄄sis showed that the hydrogen protons could enhance the dielectric constant of the passive film and account for the increase in capacitance and carrier density of passive films. In addition, the passive current density decreased and the carrier densities increased with the increment of hydrogen charging current.
