Influence of surface roughness on tribological characteristics of ultra-high molecular weight polyethylene (UHMWPE) was investigated by using a pin-on-disc tester. Newly-design surface profile with super-smooth surface and submicron grooves was proposed in order to apply for metallic bearing surface. The newly-design surface improved a lubricating condition, however, deteriorated the wear of the UHMWPE due to the increase in the microscopic surface roughness. It was clear that the surface profiles on Co-Cr-Mo alloy changed morphology and size of wear debris of the UHMWPE and the amount of wear of the UHMWPE.
