<p>A method of creating a porous surface region on a metal substrate involves applying a material that comprises aspherical metallic particles on to at least one surface of a porous construct, thereby forming a coating on the construct. The method can involve processing a green body comprising a powder mixture in which a metal powder and a space filler assume respective positions, comprising applying a material that comprises aspherical metallic particles to at least one surface of the green body, thereby forming a coating on the green body. Such methods may further comprise sintering the green body, thereby forming an implant. The porous coating products can be used in orthopaedic implants to increase friction between such implants and bone while providing a network of interconnected pores for secure fixation of the implant to bone by the ingrowth of bone tissue.</p> |
