EVALUATION OF PROTECTING PROPERTIES OF EPOXY COATINGS ON NAVY STEEL BY ELECTROCHEMICAL IMPEDANCE ESPECTROSCOPY

Electrochemical Impedance Spectroscopy (EIS), open circuit potential (o.c.p.) measurements and saline fog chamber experiments were employed to study the protective action of four epoxy coatings on navy steel immersed in artificial seawater. From EIS data such as pore resistance, coating capacitance,...
