发明名称	VERSCHLEISSARMER GLEITPARTNER FUER EIN KERAMISCHES GELENKENDOPROTHESENTEIL SOWIE VERFAHREN ZUR HERSTELLUNG DESSELBEN
摘要	The sliding partner for joint endoprostheses which are used in orthopaedics for joint replacement is produced from a biocompatible, crosslinked polyurethane of high strength. In order to reduce the friction and wear, a granular powder of a hard, crystalline bioceramic material is added to the polyurethane. The particle size of this biocompatible ceramic powder is in the range of 50-500 mu m, and it is present in the composite for the sliding partner to the extent of 10-80%. The technique or method of producing the sliding partner is chosen such that one of the surfaces of the crystals is in each case arranged on the surface of the joint part exposed to friction tangentially relative to the surface. <IMAGE>
