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.

这项研究工作的目的是通过使用对流-分散-反应方法模拟界面双氧分压，开发一种考虑到碎屑层和粘合剂磨损的扩展摩擦能量磨损方法。该多物理场模型可以局部估计微动界面是否在胶粘剂或磨料磨损条件下运行。对于每种情况，都要考虑特定的能量磨损系数，该系数最终可以模拟复合粘合剂磨料（W形）的微动疤痕。与以前的Ti-6Al-4V圆柱对平面微动磨损实验观察到很​​好的相关性。该模型还预测了从纯磨料到磨料-胶粘剂响应的转变，
