The present paper bears on a numerical model of steady-state behaviour of a single corrosion pit in CO2-containing media in the presence of acetic acid (17mM NaCl, 600 ppm CH3COOH, 1 bar CO2). The kinetics of electrochemical reactions occurring on the electrode surface is described by Tafel equations fitted to experimental data obtained on API 5L X65 pipeline steel. Simulation results provide an interesting insight into both the chemistry and electrochemistry inside the active pit. Particular attention is paid to the effect of HAc on the coupling behaviour between the attack base and the outer surrounding surface and to the comparison with experimental data obtained in similar conditions.
