Abstract

Abstract: The purpose of this research work is to develop an extended friction-energy Wear approach taking into account the presence of debris layer and adhesive wear by simulating the interfacial di-oxygen partial pressure using an Advection-Dispersion-Reaction approach. This multiphysics modeling estimates locally if the fretted interface is running under adhesive or abrasive wear condition. For each situation, a specific energy wear coefficient is considered which finally allows the simulation of the composite adhesive-abrasive (W-shape) fretting scar. A good correlation is observed with former Ti-6Al-4V cylinder-on-flat fretting wear experiments. This model also predicts the transition from pure abrasive to abrasive-adhesive response, W-shape and U-shape fretting scar profiles and for the first time provides reliable estimations of the maximum wear depth extension.
