Production of porous coating on a prosthesis

摘要: Preselected surface areas of a prosthesis are covered by blend matching primary metallic particles and expendable particles. The compressed heated to assure that deformation metallurgical bonding occurs between them the boundaries prosthesis. Porosity is achieved removal material. result coating including discrete bonded separated network interconnected voids presenting homogeneous porous about substrate. It has strength suitable for bone implant usage without intermediate adhesives, adequate porosity promote subsequent ingrowth.
