Fretting wear is frequently modeled using the Archard equation. The primary reason for this is that the equation is widely used and it is easy to determine the input variables. Unfortunately, the equation does not match well with experimental data about fretting. One discrepancy between the fretting phenomenon and Archard theory is commonly discussed: the [...]

Lubricants can be used to reduce fretting wear, but they will generally not eliminate the problem entirely. This is because the velocities in a fretting contact are low and motion is intermittent. As a consequence a full lubricant film cannot form in a fretting contact. One option is to stop the fretting motion entirely. If [...]
