| Abstract: | The EIS characteristics of soil corrosion for carbon steel in neutral soil were summarized.EIS of localized corrosion was composed of two capacitive semi circles and included inductive arc or diffusion impedance occasionally.EIS of uniform corrosion was composed of a single capacitive arc which included two time constants.At the same time,the influence of moisture content on the soil corrosion behavior of carbon steel was discussed.It was concluded that,in neutral soil,the charge transfer resistance in soil with moderate moisture content was smaller than that of low or high moisture content;the resistance of corrosion product layer decreased with increasing mositure content;the corrosion reaction in soil with low,moderate and high moisture content was controlled by anode reaction,cathode reaction and combination of anode and cathode reaction,respectively. |
