This work compares three electrochemical techniques, linear polarisation resistance (LPR), electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN), used in the study of corrosion of X52 steel samples in an environment containing a culture of sulphate reducing bacteria (SRB). The study emphasises the different electrochemical information obtained when using these techniques in MIC studies.
