Simulating and accelerating properties of ku'erle soil simulated solution

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.
