Abstract
The method and material of this invention eliminates the necessity of removing imbedded particles remaining after shot blasting by providing a method for surface finishing an orthopaedic implant wherein the blasting medium is bioactive. The surface finishing with bioactive material may also be used to clean the porous surface after sintering or diffusion bonding. Since the particles are made from bioactive material, it is not a concern if particles remain in the porous surface after blasting.
