In recent years the use of nanotechnological methods for all types of coatings has become increasingly important. Nanoparticles from sol-gel systems or from commercial dispersions as well as different types of nanocapsules or nanotubes may nowadays be used in order to develop novel coating systems or to improve the protective ability of conventional coating systems. The corrosion research group at the DECHEMA Research Institute has been engaged in this field for several years. Therefore this paper aims to give an exemplified overview on the different ways of using nanoparticles in protective coatings with a special focus on materials for light weight constructions. This will cover the oxidation protection of steels in press-hardening, the sealing of anodizing layers on aluminum substrates, the production of nanofibre-enhanced oxide layers under ultrasound conditions, as well as self-healing oxide layers on magnesium alloys.
