摘要: 通过实验室埋片、浸泡、动电位极化和电化学阻抗等方法对X80钢在库尔勒水饱和土壤和模拟溶液的腐蚀行为进行了研究。结果表明，X80钢在模拟溶液中的腐蚀速率约是水饱和土壤中的4倍，这与动电位极化结果相似。同时，X80钢在模拟溶液和土壤中腐蚀的阳极反应和阴极反应都为活化控制，腐蚀过程的变化趋势一致，表明模拟溶液能够较好地反映出库尔勒土壤的腐蚀特性，并具有加速性。

Abstract：The corrosion behaviors of X80 steel in Ku'erle soil with saturated water and the simulated solution were investigated by immersion, potentiodynamic polarization curve and electrochemical impedance spectroscopy (EIS). The results showed that the corrosion rate in the solution was about fourfold for that in the soil, which was consistent with that of potentiodynamic polarization curve. Moreover, the corrosion behaviors were similar for X80 steel in Ku'erle soil and the simulated solution, and the anodic and cathodic reactions were both controlled by active polarization, and the corrosion processes in both system were almost the same. These results indicated that the simulated solution could exhibit the corrosion character of Ku'erle soil. Moreover, the solution had an obvious accelerating property.

Key words： Ku'erle soil X80 pipeline steel simulated solution simulating properties accelerating properties
