| Abstract: | Methods for manufacturing metal foams and other porous metallic structures are reviewed. Liquid metal can he foamed directly by injecting gas or gas-releasing blowing agents,or by solid-gas eutectic solidification. Investment casting, infiltration under pressure or vacuum, spray forming, and melting of powder compacts which contain a blowing agent could also be used for making metal foams. The sintering method,and metal powder slurry foaming can make metal foams even in the solid state. And electro-deposition and metal vapour deposition could also be applied to create highly porous metallic structures. Finally ,various applications of metal foams are discussed. |
