Characterization of Surface Oxidation and Corrosion Processes at the Nanoscale
CNRS - Chimie ParisTech
Corrosion-induced failures of materials are observed at the macroscopic scale, but corrosion processes are surface processes taking place at the nanoscale and initiated at the atomic scale. Understanding corrosion of metal surfaces at atomic/nanometric scale is a key to a better design and an improved control of engineering metals and protective coatings. This talk will focus on a surface science approach of corrosion and protection of metals and alloys. The topics will include key factors for the stability of surface oxide films on metals and alloys and key features of organic molecule-oxide-metal interactions for corrosion inhibition. The presented data will be based on the application of advanced surface analytical techniques, combined with electrochemical measurements and DFT modeling.
