Abstract
An experimental investigation was carried out to elucidate the role of magnetic field on the wear behavior and surface roughness variations of steel/steel and brass/steel combinations under dry and oil lubricated sliding conditions. A reciprocating pin-on- plate wear testing machine was used with normal loads of either 5 N or 10 N and with maximum sliding speed of 0.03 m/s. A constant magnetic field strength of 796 A/in was applied to the rubbing surfaces during tests conducted in the presence of magnetic field. The results of the experiments show that the presence of magnetic field has a significant effect upon reducing wear rates of both tested combinations of materials under dry and lubricated sliding conditions. Furthermore. an improvement in counterface surface roughness was observed and measured due to the presence of magnetic field between sliding surfaces.
