Wavelet transform modulus maxima and holder exponents combined with transient detection for the differentiation of pitting corrosion using electrochemical noise

A potentially powerful tool to detect and classify corrosion mechanisms is the analysis of electrochemical noise (EN). Data analysis in the time-frequency domain using, e.g., continuous wavelet transform (CWT) allows the extraction of localized frequency information, providing information on the type of corrosion, i.e., uniform or localized...
