The effect of frequency on both the debris and the development of the tribologically transformed structure during fretting wear of a high strength steel

摘要

It is well established that damage to the first bodies in fretting wear gives rise to a hard and brittle tribologically transformed structure (TTS) which can influence both wear and fatigue. While the existence and significance of TTS has been established through extensive study, the underlying physical mechanisms of its formation and their dependence on fretting conditions are still not clear. The aim of this work is to investigate the role of frequency in the evolution of tribologically transformed structures in a high strength steel subjected to fretting.
