Abstract:
1. A process of forming a prosthetic implant component, the process comprising the steps of: (i) forming a prosthetic component having a shape at least approximating a desired final shape of the component from a metal alloy; (ii) subjecting the component to hot isostatic pressing followed by solution annealing to reduce grain size and pore size of the metal alloy, wherein the solution annealing includes cooling the component in a plurality of temperature reducing steps to a temperature below 800 degrees Celsius; (iii) machining the surface of the component; and (iv) electro-chemical polishing the surface of the component to remove carbides and other impurities from the surface of the component and create holes in the surface of the component, the holes having a predetermined distribution range and size range controlled by the solution annealing of step (ii).
