Physics-informed neural networks for the point defect model: Solving and inverting passive-film growth kinetics
Predicting how passive oxide films grow and break down is central to corrosion science and the long-term integrity of structural alloys, and the point defect model (PDM) is the standard kinetic description: a stiff, coupled system of Nernst–Planck, Poisson, and Butler–Volmer equations on a moving boundary; solving it c...
