Abstract
A fully alloyed porous metallic coating is applied to the surface of a metallic prosthetic component by producing a slurry comprising a suspension of the alloy in particulate form in a solution of water containing a film-forming binder material, applying to one or more surfaces of the component a coating of the slurry, forming concave and re-entrant depressions by pressing heat degradable spheres into the coating to promote fixation of the component when in use, heating the slurry to dry the same, and sintering the coated component to bond the particulate alloy onto the component, the spheres burning off during the subsequent heating or sintering step.
Claims7
A method of applying a fully alloyed porous metallic coating to a surface of a metallic prosthesis component, the method comprising the steps of producing a slurry comprising a suspension of a metallic alloy in particulate form in a solution of water containing a film-forming binder material, applying to at least one surface of the component a coating of the slurry, forming concave and re-entrant depressions by pressing heat degradable spheres into the coating to promote fixation of the component when in use, heating the slurry coating to dry the same, and sintering the coated component to bond the particulate alloy onto the component, the spheres burning off during the subsequent heating or sintering step.
