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.

Upcoming Events

Ångströms Tribomaterialdagar (Ångström Tribomaterials Days) is our premier annual event (in Swedish) where we interact with engineers representing Swedish industry and our academic colleagues. The next event is planned for 29–30 May 2013. Read more about the event here.

News

Our resarchers PhD students Maria Pettersson and recent PhD Frida Riddar were both awarded Ångström Academy's Innovation Awards of the Year, on May 16 2013, for their research with industrial and commercial potential. The awards are made possible by the economical support from Handelsbanken.Congratulations!

Our new theory explaining why a curling stone actually curls has caused a lot of interest in the press and radio. Our press release can be read here, and in a Swedish version here. The scientific paper presenting the details: The asymmetrical friction mechanism that puts the curl in the curling stone by Harald Nyberg, Sara Alfredsson, Sture Hogmark, and Staffan Jacobson was awarded the Ludema Best Paper Award at the Wear of Materials conference, held in Portland 14-18 April 2013

Frida Riddar successfully defended her thesis "Tribological aspects of pneumatic clutch actuators" on April 12 2013. Congratulations!

We have just taken on two new PhD students to the group, Magnus Heldin and Robin Elo. Welcome!

Fredrik Gustavsson successfully defended his thesis Triboactive component coatings, on February 22 2013! Congratualtions.

Congratualtions to Julia Gerth who successfully defended her PhD thesis "Tribology at he Cutting Edge" on December 7 2012! (Read more and download the thesis abstract here)"

Our PhD students Peter Forsberg and Julia Gerth were both awarded Ångström Material Academy's (ÅMA) Innovation Awards of the Year, on May 11 2012, for their research with industrial and commercial potential. The awards are made possible by the economical support from Handelsbanken.

Prof. Sture Hogmark was awarded R.F. Bunshah Award and held the ICMCTF Lecture at the 39th ICMCTF in San Diego 23–27 April 2012. See his persentation or read the extended abstract for his lecture here.
