混合润滑是一种由流体润滑剂和固体接触微凸体共同承受总载荷的接触状态。本研究的目的是耦合摩擦化学与润滑。最近的半确定性摩擦化学模型的摩擦膜生长集成在一个确定性的混合润滑模型。该模型考虑了摩擦膜的可变硬度，使润滑和摩擦化学及其相互作用的研究成为可能。将当前模型的结果与先前公布的结果进行比较。该模型可以很容易地适应实际的实验条件和几何形状。该模型可用于纯边界润滑条件以外的混合润滑条件下的摩擦膜生长监测。
Mixed lubrication is a contact condition when the total load is carried by both the fluid lubricant and the solid contacting asperities. The aim of this study is to couple tribochemistry with lubrication. A recent semi-deterministic tribochemical model of tribofilm growth is integrated in a deterministic mixed lubrication model. The model considers the variable hardness of the tribofilm and enables the study of lubrication and tribochemistry and their mutual interaction. Results from the current model are compared against the previously published results. The model can be easily adapted to actual experimental conditions and geometries. The model can be used beyond pure boundary lubrication conditions to monitor tribofilm growth under mixed lubrication conditions.
