Synthesis of orthopaedic implant materials

Patent

Description

A method for synthesis of biomedical alloys has been developed based on combustion phenomena. This low pressure combustion synthesis (LPCS) technique may be used for production of Co-based and other metal-based alloys, which cover the entire range of orthopaedic implants, including total hip and knee replacements, as well as hone screws, plates, and wires. A unique aspect of the method is that combustion synthesis under low ambient gas pressure allows one to produce pore-free (>99% theoretical density) alloys with high purity and precise chemical and phase compositions.
