Influence of magnetic field on wear in high frequency reciprocating sliding contacts

Results of experimental studies concerning the influence of permanent magnetic field on wear of dry sliding contact operating at short stroke and high frequency are presented. It was found that horizontal magnetic field with different orientations relative to the sliding direction is affecting performance of the contact. The increase in frequency of sliding reduces accumulated mass loss and lowers the surface roughness of the wear track in the presence of magnetic field. Enhanced chemisorptions of oxygen by a ferromagnetic material due to the influence of external magnetic field is postulated.
