| 摘 要： | 利用极化曲线技术、电化学阻抗测试技术等方法,研究Q235钢在含硝酸根离子土壤中的腐蚀行为.实验结果表明,硝酸根对Q235钢腐蚀的影响显著.Q235钢的腐蚀速率随土壤中硝酸根的质量分数的增加而增加,当硝酸根的质量分数增加到0.89%时,腐蚀速率达到最大;然后,腐蚀速率随着硝酸根质量分数的增加而有所减小.

| Abstract: | The corrosion behaviors of Q235 steel in soil with NO-3 ions were studied by using polarization curve technique and electrochemical impedance spectroscopy(EIS).It was found that NO-3 ions obviously affected the corrosion behavior of Q235 steel.The corrosion rate of Q235 steel increased with the increase of mass fraction of NO-3 ions in soil.As the mass fraction of NO-3 ion increased to 0.89%,the corrosion rate was the fastest.Then the corrosion rate decreased gradually with the increase of the mass fraction... |
