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 establ...

Lubrication is often employed in fretting contacts to reduce wear and stresses associated with high friction. Owing to the very small displacements associated with fretting, penetration of lubricating oils into the contact may not be effective. The e...
