Field application of electrochemical measurements with a non-invasive electrode arrangement has beenused for investigating corrosion damage and protectiveness of a paint coating on an artwork sculpture. For thisfield application solid state probes were designed and used in electrochemical impedancespectroscopy (EIS) and electrochemical noise measurement (ENM) to evaluate the level of corrosionprotection afforded by the paint coating. Samples were also analyzed in laboratory using analyticaltechniques. Results of electrochemical measurements indicated poor protective properties of the paintcoating while analytical examinations revealed an inhomogeneous structure of the coating and a highlyporous structure of the oxide scale.
