  This work overviews a new, recent success of phase-field modelling: its
application to predicting the evolution of the corrosion front and the
associated structural integrity challenges. Despite its important implications
for society, predicting corrosion damage has been an elusive goal for
scientists and engineers. The application of phase-field modelling to corrosion
not only enables tracking the electrolyte-metal interface but also provides an
avenue to explicitly simulate the underlying mesoscale physical processes. This
lays the grounds for developing the first generation of mechanistic corrosion
models, which can capture key phenomena such as film rupture and repassivation,
the transition from activation- to diffusion-controlled corrosion, interactions
with mechanical fields, microstructural and electrochemical effects,
intergranular corrosion, material biodegradation, and the interplay with other
environmentally-assisted damage phenomena such as hydrogen embrittlement.
