Welcome

to Ångström Tribomaterials Group, a part of The Applied Materials Science Division of Uppsala University. Our group conducts research and graduate education focusing on Tribology, including Surface Engineering and Materials.

Our research in tribology aims towards improving or developing new materials, coatings, surfaces structures, etc. "Better tribology" may lead to fantastic benefits in terms or quality, energy, economy, environment & health, safety, raw material savings, and much more. Please learn more about the benefits of tribological research and development and more about our research.

We teach undergraduate courses (civilingenjörskurser) on materials science, surface analysis, electron microscopy, tribology and surface engineering.
