WebJun 27, 2013 · Fretting wear – This is the wear that arises as a result of fretting which, in tribology, involves a small amplitude oscillatory motion, usually tangential, between two solid surfaces in contact Frosting – Frosting is a change in color in a restricted area of fabric caused by abrasive wear. WebFretting is a poorly understood form of fatigue caused by minute oscillating motions between materials in rubbing contact. Fretting refers to wear and sometimes 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. WebApr 1, 1994 · The problem of fretting fatigue is shown in Figs. 4 (a)-4 (c). Fretting is a time-dependent process. When acting alone, it can have a significant effect on functional capability, performance and structural integrity as well as appearance. gate-all-around
