滑动接触的两个固体之间的界面是极端环境。局部条件通常导致配合表面的组成和性质的实质性变化。这些摩擦学引起的表面改性对非常不同的机械部件和工具的摩擦学性能具有决定性影响。这些变化包括表面形貌的变化（平滑或粗糙）、微裂纹的形成、相变、变形硬化、氧化物的形成、与润滑剂添加剂反应形成固体膜、材料从相对表面的转移等，这些层和膜的厚度从原子单层到几十微米不等。由于这些改性，表面密封件、制动片、切削工具、凿岩机等的耐磨性和摩擦水平不是由原始材料提供的，而是由经过强烈改性的涂层提供的。本章概述了这一至关重要的领域。由于其复杂性和巨大的范围，这是通过展示说明性的例子，涵盖不同的材料组合，从广泛的摩擦学应用。
The interface between two solid bodies in sliding contact is an extreme environment. The local conditions typically result in substantial changes of the composition and properties of the mating surfaces. These tribologically induced surface modifications have decisive effects on the tribological performance of very different mechanical components and tools. They include topography changes (smoothing or roughening), formation of micro-cracks, phase transformations, deformation hardening, formation of oxides, formation of solid films by reactions with lubricant additives, transfer of material from the counter surface, and so on. The thickness of these layers and films range from atomic monolayers to tens of micrometres. Due to these modifications, it is not the original materials but the strongly modified layers that provides the wear resistance and friction level of face seals, brake pads, cutting tools, rock drills and so on. This chapter gives an overview of this crucially important area. Due to its complexity and enormous range, this is done by presenting illustrative examples covering different materials combinations from a wide range of tribological applications.
