ALUMINUM-BASED POROUS BODY AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2015/046623

A1

Provided is an aluminum-based porous body that uses an aluminum powder or aluminum alloy powder having on its surface an oxide coating, with these powders being strongly bonded to each other to provide a three-dimensional mesh-like structure having adequate strength; also provided is a method for manufacturing this aluminum-based porous body. A resin three-dimensional mesh-like structural body, which has a three-dimensionally linked resin skeleton wherein three-dimensionally linked connecting holes are formed by the resin skeleton, is used as a substrate. An aluminum powder and/or aluminum alloy powder is adhered to the surface of the resin skeleton of this substrate, after which heating to a temperature equal to or greater than the melting point of the aluminum powder or the aluminum alloy powder is performed in a non-oxidizing atmosphere, thereby eliminating and removing the substrate and melting the aluminum powder or aluminum alloy powder, and obtaining a porous body. The porous body thus obtained comprises an aluminum or aluminum alloy for which the density ratio of the skeleton is 90% or higher, with oxides of aluminum dispersed in the skeleton.
