A form of wear caused by vibratory or oscillatory motion of limited amplitude and characterized by the removal of fine particles from the rubbing surfaces. Fretting wear is often followed by localized oxidation, hence the term Friction Oxidation. In the case of ferrous metals, the oxidized wear particles are abrasive iron oxide (Fe2O3) that resemble rust, which has led to the term Fretting Corrosion. (See also False Brinelling). Note: Wear is damage that removes material from a surface.
