Fretting

Fretting corrosion refers to wear marks developed when gears rub against each other due to repeated vibratory micro-motion. The fretting process displaces lubricant, leading to the oxidization and rubbing away of asperities. 59 synonyms and near synonyms of fretting from the Merriam-Webster Thesaurus, plus 13 antonyms and near antonyms.

Fretting is a type of metal fatigue that occurs when two metallic surfaces are in contact with each other and is subject to rubbing. This can occur from normal movement during use. Examples are with modular hip prostheses or it can stem from vibration commonly experienced by … Fretting wear, or fretting corrosion, is a failure mode of considerable practical significance. Fretting corrosion is also called “friction oxidation,” “bleeding,” “red mud,” and “fit corrosion.” It is defined as accelerated surface damage occurring at the interface of contacting materials subjected to small oscillatory displacement. 2013-12-27 2018-05-17 Fretting corrosion is a surface damage phenomenon that is caused by small cyclic movements between two materials combined with corrosive attack from the environment. Cyclic amplitudes can be as small as 3 to 4 nm. Fretting damage such as from very small oscillating rubbing displacements can occur in a vacuum and is the result of relative micro-slip.
