Method for preparing alloy for diffusion bonding, and diffusion bonding material produced using method for preparing alloy for diffusion bonding

Abstract

The present invention relates to a method for preparing an alloy for diffusion bonding, comprising a matrix and an alloyed region having a different chemical composition from the matrix, and the method may comprise: (a) a coating step of forming an alloy precursor layer containing nickel (Ni) on the surface of a base material; (b) a surface alloying step of forming an alloyed region by mixing the base material and constituent elements of the alloy precursor layer, and (c) a polishing step of preparing an alloy surface for diffusion bonding by removing at least a portion of the alloyed region.
