1. damage to a solid bearing caused by plastic deformation resulting from overload but thought to be due to other causes, such a localized fretting corrosion; 2. local spots appearing when the protective film on a metal is broken continually by repeated impacts, usually in the presence of corrosion agents (see also Brinelling), 1. liugelaagri kahjustus ülekoormusest tingitud plastse deformatsiooni tagajärjel, kuid teistest põhjustest, nagu lokaalne korrosioonväsimus; 2. lokaalsed punktid, mis ilmnevad metallil kaitsva kile purunemisel järjestike korduvate löökide tagajärjel, sageli korrodeeruvate ainete olemasolul
