摘要
利用极化曲线技术和电化学阻抗测试技术,研究了X70钢在含不同浓度氯离子土壤中的腐蚀行为.实验结果表明:氯离子对X70钢腐蚀的影响显著.随着土壤中氯离子浓度的增加,X70钢的腐蚀速率也增加.当土壤中氯离子增大到0.3%时,腐蚀速率最大,而后X70钢的腐蚀速率随着氯离子浓度的增大而减小.
The corrosion behavior of X70 steel in soil with different Cl^- is studied by means of polarization curve technique and Electrochemical impedance spectroscopy （EIS）. It is found that Cl^-obviously affects the corrosion behavior of X70 steel. The corrosion rate of X70 steel increases with the increasing of Cl^- in the soil and reaches a maximum when Cl^- is 3% , then decreases with the increasing of Cl^-.
