Wear by abrasion is due to hard particles that are forced against and move along a solid surface and is the costliest and most damaging of the wear mechanisms. Adhesive wear occurs when a surface and its complementary component come...

..., hence the term “fretting wear” or “fretting corrosion” is applied to the phenomenon. The movement is usually the result of external vibration, but in many cases it is the consequence of one of the members of the contact being subjected to a cyclic stress (that is, fatigue), which gives rise to another...

However, once this motion is detected and measured (in amplitude), changes in design or operation can be made to prevent the fretting motion...
