Localized Corrosion Under Atmospheric Conditions: Insights from Modeling and Experiment
Robert G. Kelly, University of Virginia, Charlottesville, USA
Atmospheric exposures are the most common form of environmental that structural materials encounter. They share with localized corrosion similar experimental challenges: electrolytes of very restricted volume the composition of which controls the propagation or repassivation of localized corrosion the metal(s) in which they are in contact. Shared computational challenges include the selection of the governing equations, establishing accurate electrochemical boundary conditions, and the means of calculating evolving electrolyte composition. This talk will review some of the work in my group over the years that have tried to provide insights into engineering-relevant conditions of geometry, material, and environment through the use of experimental and computational tools. Examples will be presented include stainless steels used for spent nuclear fuel storage, dissimilar metal fastener-hole combinations as occur in aerospace construction, and coatings on aerospace aluminum alloys that use both galvanic and chemical mechanisms to provide protection.
