Abstract  A technique for determining corrosion current density Ⅰ_(corr) and anodic and cathodic Tafel coefficient b_a and b_c based on the data on cathodic polarization curve in weak polarization region was suggested. The influence of pH value and Cl~--eoncentration on the electrochemical behavior of Fe te corrosion process in acid solutions was studied by using this technique, and the results obtained were verified, by the data in strong polarization region. It is shown that OH~- and Cl~- both take part in the anodie dissolution process Of Fe with reaction orders of 1 and 0.5 respectively, and the values of b_a and b_c are 40 mV/decade and 120 mV/deeade respectively. A kinetic model for the anodic dissolution reaction of Fe in Cl~--containing acid solutions was suggested. It is also demonstrated that there is no significant interaction between the influence of pH value and Cl~--concentration on E_(corr) and Ⅰ_(corr).
