| Abstract Scope |
Cryogenic transfer atom probe tomography (APT) and atomic force microscopy (AFM) offer powerful, complementary capabilities for nanoscale analysis of corrosion and oxidation processes. Cryo-transfer preserves environmentally sensitive features—such as hydrated corrosion products, passive films, and interfacial chemistries—by minimizing artifacts introduced during specimen preparation and exposure to ambient conditions. This is especially critical for studying alloys where surface reactions evolve rapidly upon environmental exposure. APT enables three-dimensional compositional mapping of corrosion fronts and interfaces with sub-nanometer resolution, while AFM provides high-resolution topographical imaging to reveal surface features such as pits, cracks, and passive film degradation. Together, these techniques facilitate correlative analysis of both chemistry and morphology, offering insights into corrosion initiation, localized attack, and the influence of nanoscale heterogeneities. This talk will highlight recent advancements in combining cryo-APT and AFM to investigate early-stage corrosion and oxidation mechanisms in structural and functional materials. |
