Fig. 9 shows EIS plots with times for the stainless steel in the soil
containing SRB and 3.0% chloride ions. After burying for 1 day, a single
capacitive loop with a large radius was observed, and there was
only one time constant in the Bode plots, which indicates that the
passivating film was stable. No pitting was observed. After burying
for 4 days, only one capacitive loop was observed in the Nyquist
plot, but there were two time constants in the Bode plot, which
indicates that the pitting corrosion had occurred.
After the experiments, no pitting was observed on the steel
being buried in the soil without SRB, as well as in that containing
only 0.05% chloride ions with SRB. However serious pitting
corrosion was observed for the steel being buried in soils contain-.
