Abstract The electrochemical behavour of iron in carbon dioxide solution was studied using electrochemical polarization curves and AC impedance measurements.The corresponding mechanism was discuessed.Car-bon dioxide inhibited the dissolution of iron and accelerated the evolution of hydrogen.The relationship between the corrosion potential or the corrosion rate obtained by the low polarization region curve-fitting technique and the partial pressure of carbon dioxide was in accordance with the theoretical deduction.
