ABSTRACT:
A method and apparatus for a prosthesis. At least a portion of the prosthesis is made from a ceramic that is treated with ion implantation, which causes a controllable, bilateral compressive stress of the ceramic. A diamond-like-coating (DLC) can be coated on the ceramic and in the same chamber as the ion implantation. After treating by ion implantation and coating with DLC, the ceramic will be strengthened and have a low coefficient of friction and thereby be made much less likely to fracture under load.
