本文报道了纯铁和API X-65 5L管线钢在4.0wt%NaCl溶液中暴露40 min和12 h后的阳极溶解研究结果。电位-时间，电化学阻抗谱，动电位极化，计时电流-时间在恒电位技术。结果表明，在相同条件下，铁电极在氯化物试验溶液中的腐蚀速度比API X-65 5L钢快。将电极的暴露时间从40 min增加到12 h，表明铁和钢在4.0 wt % NaCl溶液中的腐蚀参数显著降低。结果一起清楚地证实，X-65钢在氯化钠溶液中的抗腐蚀性能优于铁上级。
In this work, the results obtained from studying the anodic dissolution of pure iron and API X-65 5L pipeline steel after 40 min and 12 h exposure period in 4.0 wt % NaCl solutions at room temperature were reported. Potential-time, electrochemical impedance spectroscopy, potentiodynamic polarization, and chronoamperometric current-time at constant potential techniques were employed. It has been found that the iron electrode corrodes in the chloride test solutions faster than the API X-65 5L steel does under the same conditions. Increasing the exposure period for the electrodes from 40 min to 12 h showed a significant reduction in the corrosion parameters for both iron and steel in the 4.0 wt % NaCl solution. Results together confirmed clearly that the X-65 steel is superior to iron against corrosion in sodium chloride solutions.
