Method for producing nickel alloy porous body

Abstract

A method for producing a nickel alloy porous body includes a step of applying a coating material that contains a nickel alloy powder of nickel and an added metal, the nickel alloy powder having a volume-average particle size of 10 μm or less, onto a surface of a skeleton of a resin formed body having a three-dimensional mesh-like structure; a step of plating with nickel the surface of the skeleton of the resin formed body onto which the coating material has been applied; a step of removing the resin formed body; and a step of diffusing the added metal into the nickel by a heat treatment.

1 . A method for producing a nickel alloy porous body comprising:
 a step of applying a coating material that contains a nickel alloy powder of nickel and an added metal onto a surface of a skeleton of a resin formed body having a three-dimensional mesh-like structure;   a step of plating with nickel the surface of the skeleton of the resin formed body onto which the coating material has been applied;   a step of removing the resin formed body; and   a step of diffusing the added metal into the nickel by a heat treatment.   
     
     
         2 . The method for producing a nickel alloy porous body according to  claim 1 , wherein the added metal is at least one metal selected from the group consisting of Cr, Sn, Co, Cu, Al, Ti, Mn, Fe, Mo, and W. 
     
     
         3 . The method for producing a nickel alloy porous body according to  claim 1 , wherein at least a surface of the nickel alloy powder is oxidized. 
     
     
         4 . The method for producing a nickel alloy porous body according to  claim 1 , wherein the coating material that contains the nickel alloy powder further contains a carbon powder.
