摘要： A method for generating a closed-pore metal foam and a component in which such a metal foam is used are provided. To form the metal foam having closed pores, the component is provided with a composite of metal particles that may have a layer of a blowing agent. Alternatively the metal and the blowing agent can also be arranged in layers of a sheet, or as a mixture of particles. A heat treatment is the applied whereby the blowing agent liberates a propellant gas, the blowing agent including fullerenes or nanotubes to which the blowing agent is chemically or physically bound. Due to the high temperature stability of the nanotubes or fullerenes, blowing agents may be thereby generated which liberate propellant gas at temperatures of above 1000 DEG C., such that even metals with high solidus temperatures of above 1000 DEG C. may be processed to metal foams.

摘要： A method for preparing an implant having a porous metal component. A loose powder mixture including a biocompatible metal powder and a spacing agent is prepared and compressed onto a metal base. After being compressed, the spacing agent is removed, thereby forming a compact including a porous metal structure pressed on the metal base. The compact is sintered, forming a subassembly, which is aligned with a metal substrate portion of an implant. A metallurgical bonding process, such as diffusion bonding, is performed at the interface of the subassembly and the metal substrate to form an implant having a porous metal component.

摘要： A porous near-net-shape metallic parts with an open porosity of at least 10% by volume is made by first forming an injectable mass of a metallic powder of stainless steel, Ti, NiTi, or a titanium alloy, at least one thermoplastic binder, and at least one place holder. The mass then injection molded into the shape of the part to be produced, cooled, set in a capillary-active material, and subjected to a first-stage binder removal to produce an open porosity. The place holder is then removed at least partially from the part with a fluid, and the part is subjected to a thermal binder-removing process. Finally the part is sintered.
