Epoxy model coatings were investigated while immersed in a 3% NaCl solution using Electrochemical Impedance Spectroscopy (EIS) during the first stage of the exposure where water uptake is the main process and during long term exposure. where the corrosion starts. The analysis of the impedance measur

โฆ Synopsis
The performance of the time domain method for electrochemical impedance spectroscopy is investigated with respect to amplitude overload of the perturbation signal used. Model calculations, based on the Butler-Volmer equation to simulate the nonlinearity of the electrochemical cell and experimental impedance spectra measurements are described. A comparison of the time domain and the frequency domain method for impedance spectrometry is presented and discussed.
