Examples of third body formation in sliding metal surfaces

Dienwiebel, Martin

Abstract (englisch):
Sliding induces severe changes of the material with respect to topography, composition and microstructure by mechanical mixing of the tribocouples with the lubricants and additives [1]. This new material differs, depending on the tribological system, strongly from the original materials and as a result influences the friction and the wear performance of sliding components significantly. This talk will present examples of combined in-situ tribometry experiments and atomistic simulations that improve our understanding of nanoscale interfacial processes in metallic tribo couples and coatingsThe combined experimental and simulation data allowed a look at the third body formation of tungsten and tungsten carbide [2,3], wear particle formation [4] and metallic multilayers [5].
