Tribo-magnetization is the phenomenon of magnetizing frictional surfaces by tribological actions on ferromagnetic materials. In this report, the relationship between the magnetization of frictional surface and wear phenomena is discussed for Ni. The experiments were performed by a pin-on-block sliding test. The magnetization of frictional surface is examined by measuring changes of magnetic flux density on the frictional surface. Influences of lubrication and normal load on changes of magnetic flux density are investigated. In addition, in-situ experiments for the observation of magnetic domain were performed by a powder pattern method. The results of experiments show that wear particles and transfer particles on the frictional surface are cause of the tribo-magnetization on the frictional surface. Furthermore, the movement of the magnetic domain wall right under the frictional surface is observed by in-situ experiments.
