Institute I: General Materials Properties
Coatings are widely used in the industry, as they can significantly increase the performance of the products that they are deposited on. The applications range from nanometer thick layers deposited on glass panels in order to tweak their electromagnetic transmission spectrum, to micrometer thick diamond-like carbon films deposited on highly stressed components in order to improve their reliability. Typical micromechanical tests involve scratching with a nanoindenter tip and using microbeam experiments to measure their fracture toughness. Films as thin as 50 nm can also be mechanically characterized using bulge tests. The comprehensive analytical equipment of the laboratory allows investigating the composition of the films and their adhesion properties.
