Abstract  The electrochemical behavior within the SCC cracks of 30CrMnSi steel in 3.5%NaCl solution or in 5%K_2Cr_2O_7+0.1%NaCl solution was studied. The distribution of potential, pH value and Cl~- concentration under different polarized potentials was measured. It was found that the crack tip potential versus pH value and the potential-versus Cl~- concentration relationships are both linear. Based on the electrochemical model of microcell and multi-electrode system, the electrochemical difference between corrosion crack and crevice was explained and the correlation between electrochemical behavior within the crack and the cracking sensitivity was established.
