Investigates friction and wear of epoxy composites under magnetic influence, suggesting material improvement.
There is increasing demand to develop the bearing materials of moving surfaces that perform under effect of magnetic field. Experiments have been carried out in the present work to study the effect of magnetic field on the friction coefficient and wear displayed by the scratch of epoxy composites filled by nanoparticles of metallic materials such as, iron (Fe), copper (Cu) and aluminium (Al). It was observed that friction coefficient decreased with increasing nanoparticles content at no magnetic field. The highest values were displayed by unfilled composites. Filling epoxy by Al displayed lower friction coefficient than that observed for Fe and Cu filled epoxy composites, while wear of epoxy filled by Al nonoparticles showed higher values. Friction coefficient slightly increased with increasing the intensity of magnetic field, where iron filled composites displayed the highest values. Wear showed slight decrease with increasing the intensity of magnetic field.
