摘要:
The present invention provides a method of producing a bonded body of a beryllium member and a copper or copper alloy member, in which the bonding strength and thermal cycle resistance property are further increased. When the beryllium member and the copper or copper alloy member are bonded to each other, a thin layer of titanium, chromium, molybdenum, or silicon is formed as a diffusion inhibition layer on the surface of the beryllium; a copper layer is formed as a bonding layer on the surface of the diffusion inhibition layer; a thin layer of aluminum or zinc is formed as a bonding promotion layer on the surface of the bonding layer; and the beryllium member and the copper or copper alloy member are diffusion bonded to each other with the intermediate layer formation side being the bonding surface.
