Examples of third body formation in sliding metal surfaces

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].
