    Abstract

    The use of coupled multi-electrode arrays in various corrosion applications is discussed with the main goal of advancing the understanding of various corrosion phenomena. Both close-packed and far-spaced electrode configurations are discussed. Far-spaced electrode arrays are optimized for high throughput experiments capable of elucidating the effects of various variables on corrosion properties. For instance, the effects of a statistical distribution of flaws on corrosion properties can be examined. Close-packed arrays enable unprecedented spatial and temporal information on the behavior of local anodes and cathodes. Interactions between corrosion sites can trigger or inhibit corrosion phenomena and affect corrosion damage evolution.
