Fretting is damage caused by low amplitude vibration and/or small oscillations between two surfaces in contact with each other. This damage often goes unnoticed for a long time. Over long periods, particularly at high temperatures or in corrosive environments, this friction can lead to fatigue cracking and loss of component functionality.
