Tribocorrosion is a material degradation phenomenon resulting from interactive effects between wear and corrosion. It is commonly found in engineering applications (e.g. biomedical implants and marine equipment) which involve relative motion of contacting metals in a corrosive environment. In this study, models describing tribocorrosion of passive metals in sliding contacts were reviewed. Different categories of models (two-body or three-body contact models, lubricated tribocorrosion model, empirical models, multi-degradation models) were found in the literature. Through the identification of relevant chemo-mechanical degradation mechanisms, robust analytical expressions accurately predicting the overall material loss in tribocorrosion have been developed. Numerical methods have been used to describe time dependent transitions in tribocorrosion. Possibilities and limits of the proposed models in the literature as well as future trends are discussed in this review.

钝化金属的摩擦腐蚀建模–综述

摩擦腐蚀是由于磨损和腐蚀之间的相互作用而导致的材料降解现象。通常在涉及腐蚀性环境中接触金属相对运动的工程应用(例如生物医学植入物和海洋设备)中发现。在这项研究中,描述了滑动接触中钝化金属摩擦腐蚀的模型进行了回顾。在文献中发现了不同类别的模型(两体或三体接触模型,润滑的摩擦腐蚀模型,经验模型,多降解模型)。通过确定相关的化学机械降解机理,已经开发出准确预测摩擦腐蚀中总体材料损失的可靠分析表达式。数值方法已被用来描述摩擦腐蚀中与时间有关的转变。
