Electrochemical noise analysis of corroding surfaces provides useful information regarding the temporal changes in material degradation, corrosion mechanisms and condition monitoring. In this study, we analyzed the electrochemical potential and current noise originating from the corrosion of carbon steel (ASTM A106) in distilled water using multifractal analysis. The empirical Legendre spectrum and large deviation singularity spectrum are determined for the electrochemical noise at different stages of corrosion. A wavelet-based multifractal model is introduced to describe the multiscaling behaviour.
