Fretting occurs when two contacting surfaces are submitted to small amplitude displacements (few micrometers to few hundreds of micrometers). Depending on the normal stresses and the displacement amplitudes, two types of damage may occur: formation and ejection of debris or crack nucleation and propagation. In this study, we focus on the nucleation of cracks in Ti–6Al–4V alloy under fretting-wear...
The selection of low friction coatings is of great interest to industrial applications. Nevertheless, regarding the lifetime of the coatings, the selection criteria often depend on the experimental apparatus and contact configuration and then cannot be applied to real cases. In this study, we use a model based on the local dissipated energy due to friction under gross slip conditions in fretting wear...
