METALLIC POROUS BODY, AND METHOD FOR PRODUCING SAME

摘要

Provided is a metallic porous body exhibiting excellent corrosion resistance compared to conventional metallic porous bodies formed from a nickel-tin binary alloy and metallic porous bodies formed from a nickel-chrome binary alloy. A metallic porous body at least containing nickel, tin, and chrome. One example of a method for producing such a metallic porous body is a method involving: a conductive cover layer formation step in which a conductive cover layer containing chrome is formed on the surface of a porous body base material formed from a resin material; a metal layer formation step in which a nickel layer and a tin layer are formed in a given order on the surface of the conductive cover layer; a removal step in which the porous body base material is removed; and a dispersion step in which the metal atoms in the nickel layer and the tin layer are dispersed between the nickel layer and the tin layer by being subjected to heat treatment, and the chrome contained in the conductive cover layer is dispersed into the nickel layer and the tin layer.
