Title:
METHOD FOR MANUFACTURING METAL POROUS BODY HAVING POROUS SURFACE
Document Type and Number:
Japanese Patent JP2020169363
Kind Code:
A
Abstract:
To further increase the specific surface area of a three-dimensional mesh metal porous body having a porous surface.SOLUTION: The method for manufacturing a metal porous body manufactured by the following two methods comprises: impregnating 1) a metal porous body manufactured by subjecting a foam resin sheet to electrolytic plating to heat and eliminate the resin or 2) a metal porous body manufactured by similarly impregnating the resin sheet with metal powder slurry and high temperature heating and sintering the resin sheet with a metal salt solution having same metal as the metal; heating the metal porous body in an oxidative atmosphere to form an oxide film on the surface; simultaneously decomposing the metal salt into oxide powder to be deposited; rolling the metal porous body to induce volume shrinkage and the occurrence of cracks in the oxide film; and modifying the composite oxide film into porous metal in a reducing atmosphere to increase a specific surface area.SELECTED DRAWING: Figure 1
