Fig. 8: Bode diagrams measured regularly during 7 days of continuous cathodic polarization at −0.8 V vs SCE of DH36 steel.

The modulus in (A) and phase in (B) are plotted in function of the frequency and corrected for Re (electrolyte resistance). Measurements are made after 1 h, 12 h, 36 h, 84 h, 108 h, 132 h, and 168 h of immersion at 20 °C, under static condition and natural aeration.
