This paper is the first in a series of studies on the effects of magnetic field on fretting wear damage of ferromagnetic materials. The effect of frequency of fretting vibration was tested in ranging 10 to 150 Hz under the basic Hertz-type contact between a steel ball and a steel plate. Two levels of magnetic fields of 0.08 and 0.22 T were applied with DC electronic magnets. The effects of worn volume and worn depth were examined through factors of frequency and number of cycles of fretting vibration, and morphology of appearance of worn surface. As a result, the following conclusions were derived: magnetic field increases fretting wear damage at lower frequencies, and decreases it at higher frequencies. The deference in the amounts of fretting wear debris formation is examined.
