Basic Mechanisms of Sliding Friction and Wear

本文研究了影响金属和合金滑动摩擦和磨损的基本冶金机制。先前的结果已经确定了一系列事件，包括塑性变形、局部转移、机械混合和碎屑产生。这些观察结果将用于建立基于物理现象的磨损方程。对滑移产生的机械混合材料的结构、组成和性能进行了进一步的研究。其中一些工作将与斯坦福大学的W. D. Nix合作完成。此外，半导体材料的滑动行为将被检查。n型和p型材料的变形和断裂行为的差异将导致它们的摩擦和磨损行为的差异。

This research is concerned with the basic metallurgical mechanisms that affect sliding friction and wear of metals and alloys. Previous results have identified a sequence of events which include plastic deformation, local transfer, mechanical mixing and debris generation. These observations will be used to develop wear equations based on physical phenomena. Further research is proposed on the structure, composition and properties of the mechanically-mixed material generated by sliding. Some of this work will be performed in cooperation with W. D. Nix at Stanford University. In addition, the sliding behavior of semiconductor materials will be examined. Differences in deformation and fracture behavior of n- and p-type materials are expected to lead to differences in their friction and wear behavior.
