ing higher amount of chloride ions with SRB. In other word, SRB
enhanced the pitting susceptibility of the stainless steel in soils
containing chloride ions.
3.5. Analysis of corrosion products
Figs. 10 and 11 show the surface morphology of the stainless
steel buried for 136 days in soils containing 0.5% chloride ions with
and without SRB. The photo shows that the corrosion products
were rough and loose. The pitting corrosion can be clearly observed
on the surface of the exposed steel buried in soils with SRB and
few pit holes for that without SRB. The pitting started at certain
