| 摘 要： | 采用电化学测量技术研究了316不锈钢在通高纯氢气的稀盐酸中的腐蚀行为，极化曲线和电化学阻抗谱测定结果表明，316不锈钢在腐蚀电位下处于活化区，其表面能形成多孔的腐蚀产物膜，氢渗入不锈钢试样表面将导致腐蚀阻力减小，且试样表面层的含氢量随腐蚀的进行而增加，SO4^2-对316不锈钢在测试介质中的腐蚀有抑制作用。

| Abstract: | The corrosion behavior of 316 stainless steel (316SS) in 0.01 mol/L HC1 solution aerated with hig hly purified hydrogen gas was investigated with electrochemical tests. The results of polarization curves and electrochemical impedance spectroscopy (EIS) measurements show that 316SS is in active corrosion state at corrosion potential in the test solutions. It could form porous corrosion product film on its surface. Hydrogen atoms from corrosion reaction can enter the surface of 316SS specimen and thus decrease the corrosion resistance. The amount of hydrogen atoms entered specimen surface increases with the progress of corrosion. Sulfate ions can inhibit the corrosion process of 316SS in above dilute HC1 solution. |
