Two types of experiments on metastable pitting are carried out in NaCl solutions, one with galvanically coupled Al‐2% Cu and the second with 316L stainless steel under potentiostat control; the time dependence of the current is compared to simulated time series developed from the model of Part I of these two papers. The experimental and simulated time series are analyzed by several methods in order to extract defining characteristics, and specifically the degree to which interactions among metastable pitting events are present. The similarity between the model and the experiment, particularly of the stainless steel data, is strong, most important when the intermittent transitions between low and high activity metastable pitting regions are considered. Depending on the experimental conditions, large deviations from the Poissonian statistics are observed which agree with the predictions of the model.
