摘要: The invention relates to a joint prosthesis comprising two metal parts which are movable with respect one another. surfaces of the covered an abrasion layer ceramic material has hardness is greater than that carbides present in metal. worn away by layer. As result, overall wear behavior improved considerably, and surface not affected during movement. components preferably spaced apart from another at distance most 0.2 millimeter. This close fit improves action. Owing relatively thin layer, particles formed wearing process small enough be discharged into space between synovial fluid.
