| 中文摘要: |
| 用极化曲线法和电化学阻抗法,研究了模拟酸雨淋溶下黄壤中锌的腐蚀行为。结果表明:模拟酸雨对黄壤土中锌的腐蚀影响显著,锌的腐蚀速率随着淋溶模拟酸雨pH 值的减小而增加;随着腐蚀时间的延长,黄壤土中锌的腐蚀速率增大;锌在腐蚀初期的电化学阻抗谱表现为单容抗弧,随着淋入模拟酸雨量的增加,其电化学阻抗谱表现为双容抗弧,锌的腐蚀过程受活化极化控制。 |
| 英文摘要: |
| The corrosion behaviors of zinc in yellow soil leached with simulated acid rain(SAR)were studied by means of polarization curves and electrochemical impedance spectroscopy(EIS). The results indicated that SAR obviously affected the corrosion behavior of zinc in the yellow soil.The corrosion rate of the zinc increased with decreasing SAR pH.The corrosion tendency of the soil obviously increased with the leaching time of the SAR. In initial stage of the corrosion, a capacitive loop was observed in EIS, and there were two capacitive semicircles after burying for 32 days, and the control step for corrosion of zinc in the yellow soil was activation polarization process. |
