Document Type and Number:
WIPO Patent Application WO/2005/073149
Kind Code:
A1
Abstract:
A process for producing a joined member, which process is easily applicable to joining of combinations among a wide variety of members, especially joining of members having been difficult in the prior art, for example, joining of a ceramic member with a metal member and three-layer joining for a so-called sandwich structure comprising a metal member and, arranged on both side surfaces thereof, metal members or ceramic or semiconductor members, in particular, being easily applicable to joining of members to be joined without the need of any intervening matter used only for joining purposes; and a thus provided joined member. Specifically, a process comprising pressing two members to be joined, at least one of which is a hydrogen occluding member wherein hydrogen is occluded in at least surface layer portion thereof, in contact with each other so that the hydrogen occluding surface constitutes an interface of the two members and, while maintaining the pressed contact, heating the members to thereby release the occluded hydrogen, wherein the maximum characteristic resides in causing the hydrogen occluding member to function as a joining means for the joining of the two members. Accordingly, the process is also characterized in that it can be carried out without need to employ any intervening matter used only for joining purposes, such as a special joining material or a flux, besides the members to be joined.
