Electrochemical noise (EN) can be used in situ to investigate corrosion processes and to detect and monitor the corrosion of metallic materials. EN data are largely influenced by the measurement mode, the surface area of the working electrodes, the electrolyte resistance, and the symmetry of the electrode system. Herein, the advantages and limitations of electrochemical kinetics, equivalent circuit, and shot noise methods for quantifying corrosion rates with EN are discussed.

“…One of the main application areas of the SSE is the analysis of heart signals [43,44]. However, in earlier studies [25,26,28], it was applied to perform corrosion analysis with excellent results. To calculate the SSE, ( 5) is applied [45].…”

“…Recently, Ramos-Negrón et al [25,26] introduced the use of the Stockwell Transform (ST) and the Shannon energy for analyzing electrochemical noise signals to identify the corrosion type in 6061-T6 Al in different solutions (H 2 SO 4 at 15% v/v, NaCl at 3.5% v/v, and demineralized water) at two different temperatures (NaCl 3.5% v/v at 22 °C and 75 °C).…”

This work shows the results of evaluating the corrosion type and rate (CR) in the 6061-T6 aluminum alloy exposed to ethanol-gasoline blends (E0, E10, E20, E30, E40, E60, E80, and E100) by analyzing electrochemical noise (EN) signals using the Shannon energy (SSE) and the synchrosqueezing transform (SST). The obtained results are compared against the obtained with the statistical method (Location Index, LI). The results obtained with the SSE method showed that the corrosion type in the 6061-T6 aluminum alloy is classified better than using the statistical method. Moreover, the SST results showed that the corrosion rate increased with the increment of the ethanol content in the ethanol-gasoline blends from values in the order of 10 − 4 to 10 − 3 mm/year.
