Document Type and Number:
WIPO Patent Application WO/2016/084488
Kind Code:
A1
Abstract:
Provided are: a dissimilar metal bonded structure wherein dissimilar metals of a wider variety than ever before can be bonded, while having sufficient bonding strength; a method for producing this dissimilar metal bonded structure; and a water-cooled power conversion element which is provided with this dissimilar metal bonded structure. A dissimilar metal bonded structure 100 which is provided with: a heat transfer plate 1 which is configured of aluminum; a plating layer 2 which is formed on the heat transfer plate 1 and is configured of nickel; an intermetallic compound layer 5 which is formed between the heat transfer plate 1 and the plating layer 2, and which is obtained by alloying between aluminum and nickel; and a laminated structure 6 which is formed on the plating layer 2 and is obtained by laminating a plurality of mixed molten coagulation parts 4, each of which is obtained by mixing and melting nickel and copper, in a direction that is perpendicular to the heat transfer plate 1.
