Localized Corrosion Under Atmospheric Conditions: Insights from Modeling and Experiment

Robert G. Kelly

University of Virginia


Atmospheric exposures are the most common form of environment 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 of 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 has tried to provide insights into engineering-relevant conditions of geometry, material, and environment through the use of experimental and computational tools. Examples that 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.


Robert G. Kelly is a professor of Materials Science and Engineering at the University of Virginia (UVa) since 1991. After earning his Ph.D. at Johns Hopkins University (1989), he spent two years at the Corrosion and Protection Centre at the University of Manchester as a Fulbright Scholar and Post-doctoral Fellow. His work has included the corrosion of metals and alloys in marine environments, non-aqueous and mixed solvents as well as SCC and other forms of localized corrosion. His present work includes the electrochemical and chemical conditions inside localized corrosion sites in various alloy systems, atmospheric corrosion, and multi-scale modeling of corrosion processes. He was selected for the 1997 A. B. Campbell Award, the 1999 H. H. Uhlig Award (NACE), the 2016 H.H. Uhlig Award (ECS), and the 2021 W.R. Whitney Award (NACE). He is a Fellow of NACE/AMPP and ECS. He has won several teaching awards while at UVa, including an All University Teaching Award in 2004.
