This GRANT is a Continuation of 1107926, Mechanistic studies of Intergranular Corrosion and Stress Corrosion Cracking under atmospheric conditions
Abstract
Funds are provided to understand corrosion conditions in thin films, and the effects of atmospheric variables on IGC/SCC kinetics, and to extend full immersion mechanisms to atmospheric conditions. Specific tasks include: characterize chemical and electrochemical conditions, such as the electrochemical potential in thin electrolyte layers, varying salt loading density and composition, relative humidity (RH) and ozone concentration on both corroding (sensitized AA5083) an inert (Au) surface using Scanning Kelvin Probe (SKP); develop a comprehensive set of IGC and SCC kinetics under the range of atmospheric conditions, compare the dependencies of the IGC and SCC rates on mentioned variables to the extensive database under full immersion; perform electrochemical measurements in bulk solutions and define the underlying mechanisms to provide the information needed to predict IGC and SCC rates under atmospheric conditions that were not tested.
