Effect of heat treatment on friction and tribolayer formation in copper

This work analyses the effect of annealing conditions on tribolayer formation in copper under dry sliding conditions. Cold rolled material and samples annealed during 15, 30 and 45 min at 600 °C show an increase in grain size, decrease in hardness and increase in toughness and ductility with time. Electron backscattered diffraction maps describe the severe plastic deformation of a nanostructured tribolayer. Friction coefficients decrease with annealing times, while surface damage diminishes. Wear is lower in the softer material. This is explained by the energy required to produce surface damage, in combination with the energy transmitted to the substrate by friction.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Jilt Sietsm
