| Abstract Scope |
The aim of this lecture is to present an overview of insights achieved using advanced surface structural and chemical characterization, including STM, ECSTM, STS, XPS, and ToF-SIMS on different metals and alloys, on systems of increasing complexity.
The overview will go from atomistic scale studies of passivity of well oriented single-crystal surfaces to nanoscale investigation of localized corrosion at grain boundaries, to the effect of adsorbed organic molecules to inhibit corrosion, with a constant focus on how early reaction stages at the nanoscale govern the later evolution of materials interacting with chemically aggressive environment. This approach will be exemplified for metals (Ni, Cu, Fe) and corrosion resistant alloys (from stainless steels to high entropy alloys). |
