Beginning of the repeatedly wear, severe wear condition of high wear rate becomes predominate. The wear rate decreases with time and the wear condition changes to a mild wear. After that, a wear becomes hardly advance and becomes stable condition. An oxide film forms at a worn surface and the surface geometry becomes smooth. That condition is called “running-in”. The transition mechanism from severe to “running-in” is important for constant operation of the machine that has a mobile components contacting among metals. A drying repeated wear test of a pin on disk was studied under unlubrication condition in this report. Also, a change of a running-in process in magnetic field has been studied. The results are reported as follows.
