Abstract

The influence of different temperatures on the corrosion of mild steel (MS) exposed to artificial seawater (AS) has been studied using the techniques of electrochemical noise (EN) and electrochemical impedance spectroscopy (EIS) at different temperatures. Comparisons have been made with results obtained by EIS and EN. Good agreement was observed between the noise resistances (Rn) derived from the analysis of EN in the time domain and polarization resistance (Rp) obtained from EIS. Analysis of EN data demonstrated the importance of removing drifts in the potential and current fluctuations during the measurements periods.
