Tribology
Friction, wear and lubrication of machine elements
The optimum interaction of base and mating body in so-called tribological contact is essential for a long service life of machines and systems as well as their energy-efficient and resource-saving operation. The tribology group at MSE studies the interactions between the stressed surfaces of machine components and lubricants. The focus is on fundamental research on the mechanisms, such as friction and wear, as well as the experimental and simulative methods to elucidate the behaviour of lubricants and components under tribological stress. Further research focuses are the detection and classification of wear-critical operating conditions and the prediction of degradation processes.
