| Abstract Scope |
With corrosion remaining a significant economic issue, the ability to a priori predict the kinetics of material corrosion in a high-throughput manner remains an important consideration in a wide range of energy applications which employ aqueous environments. To address this challenge, we have developed an ab initio-kinetic model (AKM) for predicting material stability by combining electronic structure and atomistic methods with a kinetic passivation model called the Point Defect Model (PDM). We explore and redefine PDM’s previously ad hoc parameters and present a viable approach to automating AKM in elemental materials with fully first principles methods. We then evaluate the efficacy of this non-empirical framework in predicting the growth rate of passivation films by applying it to four metal-oxide systems with available experimental data on film growth. |
