Abstract: The present invention provides a method for 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. The present invention also provides implants that are produced in accordance with such method.

Abstract: The present invention concerns articles having an outer surface that bears at least two layers of metal particles, wherein the at least two layers comprise an outermost layer and an intermediate layer; the outermost layer consisting essentially of aspherical metallic particles having a mean particle size of 50 to 500 microns; and the intermediate layer consisting essentially of substantially spherical metallic particles having a mean particle size of from 50 to 500 microns. In some embodiments, the outer surface has a volume porosity of between about 20% to about 80%.

Abstract: One aspect of the present invention provides methods comprising applying a material that comprises aspherical metallic particles onto at least one surface of a porous construct, thereby forming a coating on the construct. The present disclosure also provides implants that are produced in accordance with the disclosed methods. In another aspect, there are provided methods for 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 present invention also provides implants that are produced in accordance with such methods.
