| Abstract | X80 steel corrosion induced by alternating current (AC) had been investigated by surface analyses and electrochemical measurements in water-saturated acidic soils. The AC sharply increased the corrosion rate of X80 steel. Moreover, the DC potential of X80 steel shifted toward the negative direction after applying AC density, and decreased with the AC density ascending from 0 A/m(2) to 200 A/m(2). A power function model, CR = ai(n) + b, was used to reflect the relation between AC density and corrosion rate. gamma-FeOOH acting as an oxidizer weakened the protective ability of product film, and further accelerated the corrosion of steel. |
