Abstract (en)
[origin: WO8300282A1] A method of producing a porous coating (26) on preselected areas of a prosthesis (25) and the resulting implant (10) having a unique porous coating (26). Preselected surface areas are covered by a blend of matching primary metallic particles and expendable particles. The particles are compressed (20) and heated (21) to assure that deformation and metallurgical bonding occurs both between them and at the surface boundaries of the implant element (10). Porosity is achieved by removal of the expandable material (24). The result is a coating (26) including discrete bonded particles separated by a network of interconnected voids presenting a homogeneous porous coating (26) about the substrate (10).
