Abstract

Corrosion cells and first estimates of crevice corrosion behavior V.G. DeGiorgi Mechanics of Materials Branch, Naval Research Laboratory, DC ABSTRACT Computational simulations using boundary element techniques are used to determine the spatial distribution of electrical current and potential in coplanar concentric corrosion cells. Conditions of unequal depths of electrolyte above the anode and cathode are considered as well as conditions of equal depths of electrolyte. The conditions of unequal electrolyte depths are a first approximation in determining the effects of the differing volumes of electrolyte above regions of localized corrosion, such as found in cracks and crevices. Localized corrosion such as crevice corrosion is a synergistic phenomenon involving electrolyte composition, material composition as well as geometric effects. This work addresses one aspect of geometric constraint on electrochemical response. INTRODUCTION Localized corrosion is distin
