Barrier property determination and lifetime prediction by electrochemical impedance spectroscopy of a high performance organic coating
The anticorrosion performance of an Epoxy-Mastic organic coating was evaluated during continuous immersion in saline solution using electrochemical impedance spectroscopy (EIS). The typical parameters of pore resistance and charge transfer resistance were determined employing an equivalent electric...
