摘　　要：采用交流阻抗谱和极化曲线测试技术,研究了碳钢和纯铜在4种不同土壤介质中的腐蚀规律.实验结果表明,土壤配制液对碳钢和铜电极的侵蚀性与土壤溶液的pH值有较大关系.The corrosion behavior of carbon steel and copper electrodes in four different soil solutions is investigated by means of electrochemical impedance spectroscopy and polarization curves. The results show that the corrosiveness of the soil solutions to carbon steel and copper electrodes is closely related to the pH values of the soil solutions.

关 键 词：土壤腐蚀 碳钢 铜 极化曲线 交流阻抗谱
