摘要

With the increasing modernization of machinery, more and more friction parts are exposed to alternating electromagnetic fields. To investigate the impact of alternating electromagnetic fields on the tribological behavior of key components, a Helmholtz coil was incorporated into the ball/disc reciprocating friction tester as the source of the alternating electromagnetic fields. Then, the effect of alternating electromagnetic fields on the tribological behavior of the self-mating pair of GCr15 bearing steel was investigated in detail. The results showed both the coefficient of friction and wear volume increased significantly in the presence of an alternating electromagnetic fields. The underlying mechanism was explored by analyzing the changes in surface temperature, the morphology and chemical composition of the wear surface and wear debris, combined with electromagnetic fields simulations of wear debris.
