J0250102 Influence of textured bearing surface in artificial joint on factors of biological reaction

Abstract

Micro slurry-jet erosion has been proposed as a precision machining technique for the bearing surfaces of artificial joints in order to reduce the total amount of polyethylene wear and to enlarge the size of the wear debris. The micro slurry-jet erosion method is a wet blasting technique which uses alumina particles as an abrasive medium along with compressed air and water to create an ideal surface. From pin-on-disc wear tests with multidirectional sliding motions, the textured surface on a Co-Cr-Mo alloy could change the total amount of wear of polyethylene.
