WebFretting refers to wear and sometimes corrosion damage of loaded surfaces in contact while they encounter small oscillatory movements tangential to the surface. Fretting is caused by adhesion of contact … WebFretting wear is the mechanism presently attributed to the wear of femoral stems in vivo. The term fretting denotes a small oscillatory movement between two solid contacting surfaces [8]. The factors that differentiate fretting from other forms of sliding wear are the magnitude of movement and the nature of the damage caused.
