通过赫兹接触条件下的微动磨损试验，研究了磁场对铁基材料微动磨损的影响。由永磁体产生的0.01和0.13 T的垂直磁场被施加到触点。微动磨损试验的振幅为10 μm，标称平坦表面与直径为20 mm的钢球之间的接触上的法向载荷在40-100 N的范围内。实验在空气和低真空条件下进行。在空气中的试验发现，在磁场的影响下，微动痕的宽度增加。据认为，这种增加是由于在接触区内由磁场产生的磨损颗粒所引起的磨损作用。在低真空条件下进行的类似试验导致明显较小的微动损伤。提出并讨论了磁场作用下微动磨损的可能机理。
The effect of magnetic field on fretting wear of ferrous materials was examined using a fretting wear test under Hertzian contact conditions. Vertical magnetic fields of 0.01 and 0.13 T, created by permanent magnets, were applied to the contact. The amplitude of the fretting test was 10 μm and the normal load on the contact between a nominally flat surface and a steel ball of 20 mm in diameter was in the range of 40–100 N. Experiments were carried out in air and low vacuum conditions. From the tests in air, it was found that the width of the fretting scar increased under the influence of magnetic field. It is thought that this increase is due to an abrasive action by entrapped, within the contact zone, wear particles produced by magnetic field. Similar tests performed under low vacuum conditions resulted in appreciably smaller fretting scar. A possible mechanism of fretting wear under the influence of magnetic field is proposed and discussed.
