| Outline of Final Research Achievements |
In this study, intended to enhance the lubricating effect of the prosthesis by processing a high degree of femoral head sphericity. Then, the authors used an engraving electric discharge machine, EDM, and a ball grinding machine for the precision machining of the femoral head, Ti-13Nb-13Zr (F1713). Futhermore, the authors evaluated the ability of fluid film lubrication properties of the sliding components, Ti-13Nb-13Zr head and UHMWPE acetabular socket, by using of an artificial hip joint simulator.
According to this study, the followings were obtained with a joint simulator test of the newly high precision femoral head and PE acetabular socket. 1) EDM processing is effective to make the accurate femoral head of hip joint prosthesis. 2) The fluid film can be maintained effectively in the radial clearance less than 10-15um.
