Abstract: The present invention is directed to composite metal foams comprising hollow metallic spheres and a solid metal matrix. The composite metal foams show high strength, particularly in comparison to previous metal foams, while maintaining a favorable strength to density ratio. The composite metal foams can be prepared by various techniques, such as powder metallurgy and casting.

Abstract: The present invention provides a biocompatible coating comprising calcium phosphate that is functionally graded across the thickness of the coating. The coating, which preferably includes hydroxyapatite, is particularly useful for coating implants, such as dental or orthopedic implants. The functionally graded coating is generally crystalline near the interface with the surface of the implant, with crystallinity and crystal diameter decreasing toward the outer layer of the coating. The invention further provides methods for preparing a coated implant comprising a functionally graded calcium phosphate coating thereon. Furthermore, an antimicrobial agent can be dispersed within the calcium phosphate coating at discrete locations to provide for a coating with tailored release of the antimicrobial agent.

Abstract: The present invention provides polymeric substrates comprising a biocompatible coating and methods of preparation thereof. In particular, the coating may be a ceramic material, especially a calcium phosphate material, which may be functionally graded. The invention provides the ability to apply high quality coatings to polymeric substrates without damaging the substrate (e.g., melting the polymeric material). The functionally graded coating can provide crystalline calcium phosphate near the coating interface with the substrate and provide amorphous calcium phosphate at the outer surface of the coating.
