Electrochemical impedance spectroscopy (EIS) is a powerful tool in developing the most appropriate methodology for ensuring long-lasting artefact preservation. EIS consists in the measurement of amplitude and phase of the surface impedance of coated metallic objects at different frequencies in order to highlight either the protective effectiveness of a coating or the stability of a corrosion product layer grown onto the metallic surface. Two in situ EIS measuring campaigns are described together with the description of the portable instrument and the measuring probes specifically designed and developed for cultural heritage applications.

Abstract

Electrochemical impedance spectroscopy (EIS) is a powerful tool in developing the most appropriate methodology for ensuring long-lasting artefact preservation. EIS consists in the measurement of amplitude and phase of the surface impedance of coated metallic objects at different frequencies in order to highlight either the protective effectiveness of a coating or the stability of a corrosion product layer grown onto the metallic surface. Two in situ EIS measuring campaigns are described together with the description of the portable instrument and the measuring probes specifically designed and developed for cultural heritage applications.
