摘要： A method and apparatus for simultaneously and continuously monitoring both the general and localized corrosion of a working metallic electrode is provided, wherein a low frequency, low amplitude periodic potential excitation is used to perturb the electrode around its free corrosion potential. The potential is controlled with respect to a reference electrode by means of a potentiostat, and an auxiliary electrode used to stimulate current flow. The current response of the working electrode is monitored and analyzed continuously for general and localized corrosion activity. Means are provided for validation of the integrity of the current response to the applied potential excitation. Simultaneous and continuous outputs for both general and localized corrosion activity are also provided.
