Understanding fundamental mechanisms in tribocontact

© Fraunhofer IWM

The fundamental processes determining the service life and efficiency of friction contacts in technical components play out in the first hundred nanometers below the surface. Friction and wear are highly dynamic non-balanced operations, which are subject to intensive feedback. These processes can be better understood in model experiments through a combination of in-situ tribometry, surface physical and chemical measurements, and simulations.
