Abstract

The phenomenon of fretting fatigue arises as a result of surface interaction between two contacting bodies and it is therefore important to investigate the nature of the surfaces in some detail in order to understand the phenomenon in any meaningful way. Real surfaces are invariably complex and differ quite markedly from the smooth abrupt transitions from elastic solid to free space which have been assumed so far in this book. For example the surface of a metal component may consist of a number of layers, as depicted in fig. 5.1 for a typical metal. The bulk of the metal component will form a substrate. On top of this will be a layer of material which will typically have been exposed to large amounts of plastic deformation during the manufacturing process.
