Fretting (or fretting corrosion) refers to corrosion damage at the asperities of contact surfaces. This damage is induced under load and in the presence of repeated relative surface motion, as induced for example by vibration. The ASM Handbook on Fatigue and Fracture defines fretting as: "A special wear process that occurs at the contact area between two materials under load and subject to minute relative motion by vibration or some other force."
Action that results in surface damage, especially in a corrosive environment, when there is relative motion between solid surfaces in contact under pressure
Surface damage resulting from relative motion between surfaces in contact under pressure
wear occurring on mating surfaces due to slight relative motion resulting from dynamic stresses
Wear or corrosion phenomenon caused by vibration among tightly clamped or fastened surfaces
Wear phenomena occurring between two surfaces having oscillatory relative motion of small amplitude Fretting is a term frequently used to include fretting corrosion This usage is not recommended
