Predicting friction and wear

Tribology

This business unit carries out research into friction and wear. We optimize tribological systems and develop solutions that reduce friction and protect against wear with the aid of technical ceramics, innovative lubricants, tribological layer systems and tribo-materials conditioned for manufacturing technology.

We investigate friction, abrasion, running-in and wear mechanisms as they affect the tribo-chemistry of machine elements such as roller and slide bearings, cutting and forming tools or motor and gear elements. We use experimental techniques, multi-scale modeling and numerical simulations as well as microstructure analysis.

MikroTribologie Centrum µTC

The Fraunhofer IWM and the Institute of Applied Materials – Reliability of Components and Systems (IAM-ZBS) at the Karlsruhe Institute for Technology KIT cooperate with each other in the Tribology research department. The joint initiative MikroTribologie Centrum µTC combines the competencies of these two institutions in industrially relevant research, in fundamental research and in academic activities.

A particular highlight here is the customized Tribo-Contact – the key to success for energy efficiency, a long service life and cost effectiveness.
