| Abstract: |
| The corrosion behaviors of zinc in yellow soil leached with simulated acid rain(SAR)were studied by means of polarization curves and electrochemical impedance spectroscopy(EIS). The results indicated that SAR obviously affected the corrosion behavior of zinc in the yellow soil.The corrosion rate of the zinc increased with decreasing SAR pH.The corrosion tendency of the soil obviously increased with the leaching time of the SAR. In initial stage of the corrosion, a capacitive loop was observed in EIS, and there were two capacitive semicircles after burying for 32 days, and the control step for corrosion of zinc in the yellow soil was activation polarization process. |
