METHOD FOR PRODUCING MICROPORE NICKEL POROUS BODY, AND MICROPORE NICKEL POROUS BODY PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a micropore nickel porous body; to provide a micropore nickel porous body; and to provide a member product thereof.

SOLUTION: Disclosed is a method for producing a micropore nickel porous body where a starting alloy composed of two components of nickel and manganese is heat-treated at 720 to 1,020°C and is rapidly cooled, so as to produce a solid solution alloy of nickel and manganese which does not comprise brittle intermetallic compounds and is easily subjected to plastic working, and, in the prescribed molded or non-molded precursor of the solid solution alloy of nickel and manganese, only manganese is selectively dissolved away in an aqueous solution showing a neutrality of pH 4.5 to 8.5; thus a micropore nickel porous body is produced without using a strong alkaline aqueous solution. Also disclosed are the micropore nickel porous body and the member thereof. The micropore nickel porous body can be produced and provided from a master alloy which is easily subjected to plastic working using an aqueous solution at an about neutrality without using a strong alkaline aqueous solution.
