Project Details
Description
The project will advance the microscopic understanding of the principal factors controlling the evolution of self-healing passive films that form on binary alloy surfaces in aqueous electrolytes. These factors include the crystal structure, alloy composition, chemical short-range order (SRO) and the composition of the electrolyte. To that end, the project will employ an integrated computational and experimental approach to develop descriptive and predictive models of passivation that account for interactions among structure, composition, and ordering effects in exemplary sets of single-phase FCC and BCC binary alloys to the evolution, structure, and composition of primary passive films. The project will lead to advances in understanding SRO effects that are also active in multi-element alloys, enable study of fundamental processes at metal-electrolyte interfaces, and provide features to guide the future design of new alloys and protective coatings with passivation behavior superior to current materials. Results and methods employed in this project will be broadly dissemination. The project will also provide training opportunities for graduate students and postdoctoral fellows within a highly interdisciplinary environment, leading to a well-equipped workforce for Industries of Tomorrow.
