Nano-Al2O3 and micron Al2O3 reinforced polyamide 6 composites (PA6/Al2O3) were prepared via in situ polymerization. The effects of nano-particle content and wear condition on the tribological properties of the composites were measured using a MM-200 block on ring wear tester. The worn surface was investigated with a scanning electronic microscope and a metallurgical microscope and the wear mechanism was proposed. It was found that nano-Al2O3 improved the wear resistance of monomer casting polyamide 6 with the optimal content of nano-Al2O3 being approximately 3 wt.%. The wear rate of PA6/Al2O3 nano-composite was lower than that of the composite with micron Al2O3 and increased slowly while its friction coefficient decreased gradually with load. However, the friction coefficient of the composite was somewhat larger than that of monomer casting polyamide 6 and lower than that of the composite with micron Al2O3.
