Electrochemical impedance spectroscopy studies of stainless steel corrosion by two strains marine sulfate reducing bacteria

This research was conducted to compare corrosion potential of two strains of marine sulfate reducing bacteria (SRB1 and SRB2) on their effect of biocorrosion on stainless steel AISI304 using electrochemical techniques. This study was carried out using Electrochemical Impedance Spectroscopy (EIS) to...
