Abstract
In this paper, the effect of magnetic field on fretting wear under gross slip was investigated in ranging number of cycles from 102 to 105 under the Hertz-type contact of steel ball to steel plate. The amount of fretting wear volume was evaluated by wear occurring on the surface of the steel plate with and without magnetic field. The experimental results show that the wear region spreads under the magnetic field and the worn volume is increased resulting from accumulation of the wear particles near contact tracks under the magnetic field. It is concluded that the wear particles trapped along the contact annulus increase the worn volume by abrasive and/or pile up action under magnetic field.
