Phase field models have had a significant impact on many interfacial problems, including the modelling of microstructural evolution and fracture mechanics. In this work, we show how phase field modelling can also open new horizons in a scientifically-challenging phenomenon of notable technological importance: corrosion damage [1]. The phase field paradigm can be exploited to enable tracking the aqueous electrolyte-solid metal interface. This enables predicting explicitly, as a natural by-product of the simulation, the evolution of pits, the pit-to-crack transition and stress corrosion cracking. The work constitutes the first formulation capable of capturing the film rupture–dissolution–repassivation mechanism and the role of mechanical fields in enhancing corrosion kinetics. Several 2D and 3D boundary value problems of particular interest have been addressed to showcase the predictive capabilities of the model, revealing an excellent agreement with analytical solutions and experimental measurements. The results that will be presented show how the model can naturally capture: (i) the transition from activation-controlled corrosion to diffusion-controlled corrosion, (ii) the sensitivity of interface kinetics to mechanical stresses and strains, (iii) the role of film passivation in reducing corrosion rates, and (iv) the dependence of the stability of the passive film to local strain rates. Finally, the conference contribution will describe ongoing efforts aiming at generalising the model to capture: (i) microstructural effects, (ii) the electrochemical behaviour of the electrolyte, (iii) both anodic-driven and hydrogen-driven cracking mechanisms [2], and (iv) the corrosion of bio-degradable materials.
