The protection of metals and alloys against corrosion is a major issue in many respects including, but not limited to, scientific and technical aspects.
The cost of corrosion is of the order of 4% of the gross national product. The life time of products made of metallic materials is often limited by corrosion problems.
Corrosion is an issue for the durability of materials, as well as for safety, maintenance, recycling, environmental control, and health.
A better control of corrosion is thus required, and the progress in the science of corrosion is a determining factor.
Corrosion is related to the reactivity of metals and alloys surfaces in gaseous and liquid (usually aqueous) environments.
In this lecture it will be shown how a surface science approach contributes to provide a detailed understanding of corrosion at the nanoscale. The emphasis will be placed on the growth, structure and corrosion protection properties of ultrathin oxide layers formed on metals and alloys in aqueous solution, studied mainly by in situ Scanning Tunneling Microscopy and on the ab initio (DFT) Modelling of the reactivity of such oxide surfaces.
The language of the presentation is English.
Free entrance, guests are welcome
