    摘要： A medical implant component and a method for fabricating the same are provided. The medical implant component may comprise a substrate having a bearing portion, in which at least the bearing portion has a coating of at least 25 micrometers of a predetermined material. The predetermined material of the coating may include chromium ceramic having a chromium component which releases less than approximately 7 parts of hexavalent chromium per billion parts of water solution when the medical implant component is immersed in approximately 500 milliliters of water for approximately one week at a temperature in a range of room temperature to just below a boiling point of the water at atmospheric pressure. The residual stress of the coating may be less than approximately 100,000 pounds per square inch. The chromium ceramic may be a chromium oxide, a chromium carbide, a chromium nitride, or a chromium boride, or any combination thereof.

    摘要： A method of manufacturing an orthopaedic implant device having a porous outer surface is described. In one embodiment, the implant device includes a porous layer, an intermediate layer, and a solid substrate. The porous layer is preferably bonded to the intermediate layer by cold isostatic pressing. The intermediate layer is preferably bonded by vacuum welding to the solid substrate such that the porous layer forms at least a portion of the outer surface of the orthopaedic implant device. Preferably, a diffusion bond is created between the bonded intermediate layer and the solid substrate by hot isostatic pressing. In another embodiment, a porous layer is created on an outer surface of a solid layer by selective melting. Preferably, the solid layer is bonded to the solid substrate such that the porous layer forms at least a portion of the outer surface of the orthopaedic implant device.
