To Measure and Characterize Metal Corrosion in Electrolyte Solutions by Exploiting the Properties of Superconducting
Abstract
A framework relating fluctuations in an electrochemical cell to fluctuations of the fundamental thermodynamic and kinetic parameters of the system is presented. A method for extracting critical interface parameters via noise measurements, such as the charge transfer resistance, is developed. The technique, called variable load analysis, does not require perturbation of the cell with applied voltage or current. The framework suggests measurements to distinguish between different noise sources superimposed in the same signal, and to determine the mechanisms underlying the observed noise. A cell geometry with two identical electrodes connected through an external resistive load is used. Fluctuations in the current flowing between the two electrodes under open circuit conditions (i.e. under no applied external potential) provide the detected signal. Electrochemical noise.
