Chaos theory and the use of phase space reconstruction produce a novel methodology to study electrochemical noise (EN) signals, obtaining novel information to distinguish corrosion types. To evaluate the chaotic nature of electrochemical noise, phase space is reconstructed and the embedding parameter is obtained by the mutual information and Cao's methods. Subsequently, the correlation dimension is calculated. From the correlation dimension, we can conclude that local corrosion shows a higher correlation dimension while passivation shows a lower correlation dimension. (C) 2011 Elsevier B.V.
