Students gain a basic understanding of the atomistic or molecular structure of surfaces and their links with wetting, adhesion, patterning and corrosion. They learn different techniques to characterize surfaces wettability, chemical composition and topography. They receive an overview over the most current surface treatment processes for protection and aesthetics, as well as of micro/nano-patterning techniques to impart surfaces with unique electrical, optical and wetting functionalities. Finally, the students recognize the different types of corrosion, understand the underlying mechanisms and can identify appropriate protective measures (appropriate design, material choice, use of coatings, adaptation of the working environment, special electrochemical protection and monitoring techniques). Eventually, they can propose a suitable surface treatment process to tailor specific functional properties.

Fundamentals of physical, chemical and materials science.
