摘要
在实验室配制不同含水率土壤介质,利用线性极化及电化学阻抗技术,测试了Q235钢在冻土环境下的线性极化曲线和交流阻抗曲线,并对测试结果进行了分析拟合,得到线性极化电阻值和电荷转移电阻值,并与常温下Q235钢的腐蚀行为进行了对比,从而确定了Q235钢在不同含水率的冻土环境中的自腐蚀电位值以及Q235钢的腐蚀情况。
The linear polarization curves and Electrochemistry plots were measured in different containing water ratio at 0℃ and -5 ℃ in laboratory. The linear polarization and Electrochemistry results were achieved through analyzing the curves and plots. They were compared with the results which were measured at 23 ℃ and 5 ℃ in different containing water ratio, consequently the self-corrosion potential and corrosion behavior of Q235 steel in different containing water were confirmed.
