Abstract:
1. A method of manufacturing an orthopaedic implant device having a porous outer surface comprising: providing a solid layer having an outer surface and an inner surface, the inner surface having a perimeter; creating a porous layer having a porosity on the outer surface of the solid layer by selective melting; providing a solid substrate in the form of an orthopedic implant device having an outer surface and an inner surface, the outer surface having a perimeter; bonding the inner surface of the solid layer to the outer surface of the solid substrate by welding in a vacuum at an interface about the perimeters of the solid layer and solid substrate to create an initial bond about the interface such that the porous layer forms at least a portion of the outer surface of the orthopaedic implant device, the initial bond sealing the interface wherein no gas can subsequently pass through the interface; and creating a diffusion bond between the bonded solid layer and the solid substrate by hot isostatic pressing after the initial bond is created in order to maintain the porosity of the porous layer.
