Abstract
This paper describes the development of a simple circuit for the measurement of electrochemical noise, which has the potential to be routinely applied in conservation contexts, particularly for the evaluation of coatings on historic metal objects. Measurement of electrochemical noise (both voltage and current) has been performed on a range of coated mild steel samples in chloride solution, demonstrating the ability of the equipment to discern trends in the behaviour of coated metal systems and to rank coating performance. Electrochemical noise results are compared with the results of AC impedance tests performed on the same samples.
