| 摘 要： | 采用电化学和ＳＴＭ方法研究了氢对３１０不锈钢阳极极化过程，钝化膜形成过程和表面形貌特征以及膜耐点蚀性能的影响，并进行了相应的理论分析。研究表明：氢会降低不锈钢的自腐蚀电位，缩短钝化区域并使其向低电位方向偏移；降低反应电阻，增大钝化电流工，降低膜在纳米尺度上的结晶度和耐点蚀性能。

| Abstract: | The effects of hydrogen on anodic process, film formation surface character and pitting-resistance of passive film on type 310 stainless steel were theoretically analyzed and experimentally studied by use of electrochemical and STM methods. The results showed that hydrogen can decrease the inner energy of the stainless steel and its corrosion potential, narrow the passivation region and increase its anodic dissolution; decrease the reactive resistance, enhance the passive current density; reduce crystallinity of the film in nanometer scale and the pitting resistance. These influences were more noticable when increasing the pre-charged hydrogen content in the steel. WT9.,12.HZ] |
