A corrosion study has been made using the electrochemical current and potential noise
technique, polarization curves and conventional weight loss method to determine the corrosion
resistance of a carbon steel exposed to LiBr-H2O (50% wt.) corrosive solution at 25, 50, 60, 70
and 80°C. From the noise measurements, the resistance noise (Rn) was determined, and then
the Stern-Geary equation and Faraday’s Law were used to determine the mass loss. The results
indicated that the corrosion rates increased with temperature. SEM observations of the corroded
samples indicated that the carbon steel suffered localized corrosion; these results were according
to the pitting index obtained from the current time series data. To support the corrosion
mechanism, EDS analysis of the corrosion products were also made. Through the polarization
curves, the Tafel slopes were obtained together with some qualitative corrosion characteristics of
the carbon steel.
