Materials Tribology / Materialien unter tribologischer Belastung

The group focuses on materials science aspects of materials under a tribological load.

Our main research topics are:

The elementary mechanisms for microstructural and chemical changes
The materials science origins of friction and wear
Size effects
Contact mechanics
Bio-inspired materials and structures
Laser surface texturing
Data Science in tribology

In order to be able to answer these questions:

We develop and build our own equipment and instrumentation, e.g. an extremely high resolution in situ reciprocating tribometer
Make use of ultra-high resolution electron and ion microscopy, including 3D reconstruction techniques
Morphologically texture surfaces by means of laser radiation
Employ modern x-ray techniques, including from synchrotron sources
Collaborate with scientists on an international basis

With this unique combination of scientific expertise and analytical tools we aim at strategically tayloring materials and microstructures for lower friction and less wear.

We always have very attractive topics available for bachelor and master theses, so please do contact us in case you are interested in joining the group!
