| Abstract: | Fe-Cu-Al-graphite composites were prepared by induction sintering. The composition,microstructure and surface morphology of the composites were analyzed by means of X-ray diffraction,energy dispersive spectrometry and scanning electron microscopy. The mechanical properties as well as friction and wear behavior of the composites were measured.Results show that as-prepared composites have porous microstructure.The mechanical properties of the composites decreased with increasing graphite content, but their friction-reducing ability and wear resistance rose therewith. The composites containing 4%graphite possessed good wear resistance.During the friction process,a self-lubricating layer was formed on the surface of the Fe-Cu-Al-graphite composites, accompanied by transformation of wear mechanism from adhesion wear to abrasive wear. |
