Аннотация:The paper presents the results of comparative measurements of corrosion rate by Coulometric
Detection of Corrosion Products (CDCP method) and voltammetry (VA). The corrosion kinetics
was measured in the time interval where the steady potential Est is established in the “carbon
steel – 0.5 M NaCl solution” system as an example. The results of measurements by both
methods showed a considerable difference in mass losses in the time interval of specimen
surface activation. This fact was explained taking the semiconducting nature of iron oxides into
account. Thus, the disagreement may originate from different conductance mechanisms of the
metal and its oxides in a strong electric field. The CDCP method was used to determine the
conditions required for agreement of the results of potentiodynamic and coulometric
measurements.
