摘要

Corrosion degrades metals through complex microscopic processes that traditional methods often fail to capture. In situ transmission electron microscopy (TEM) bridges this gap by providing real-time, atomic- and nanoscale imaging of oxidation and corrosion dynamics. Gas-phase TEM uncovers critical oxidation mechanisms like oxide nucleation and alloying effects, while liquid-phase TEM tracks corrosion initiation. Coupled with emerging techniques like ultrafast direct electron detection cameras, these advancements promise unprecedented resolution in understanding material degradation.
