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. WebSep 1, 1988 · A fretting map is a diagram showing the relevant regimes in two variables, with regime boundaries representing critical values for the transition from one regime to another. Examples of fretting maps with vari- ation of displacement amplitude, normal and tangential force and frequency of vibration are given.
