Title: Production of Porous Coating on a Prosthesis Abstract A method of producing a porous coating on preselected areas of a prosthesis and the resulting implant having a unique porous coating. Preselected surface areas are covered by a blend of matching primary metallic particles and expendable particles. The particles are compressed and heated to assure that deformation and metallurgical bonding occurs both between them and at the surface boundaries of the implant element. Porosity is achieved by removal of the expendable material. The result is a coating including discrete bonded particles separated by a network of interconnected voids presenting a homogeneous porous coating about the substrate.
