Fretting wear example
WebThe term fretting denotes a small relative movement between two solid surfaces in contact. The surface degradation which occurs due to this motion is called fretting damage. The occurrence of fretting damage is expected in contacting surfaces of tightly fitting mechanical assemblies which experience small relative displacements due to vibration. WebNov 15, 2024 · Examples of wear can be practically found in all branches of technology where there are pairs of elements in contact that can be endangered by oscillations in …
