Joining method and joining component

摘要

In joining members to be joined (1, 1) by heating the members to be joined (1, 1) that are mated with intervening an insert (2) while applying opposing loads to the members to be joined (1, 1), so as to allow eutectic reaction to occur between the members to be joined (1, 1) and the insert (2) to discharge a eutectic melt from a joining plane along with an oxide film (1a) of the members to be joined, the members to be joined (1) are brought into contact with the insert (2) so that the oxide film (1a) is broken by a stress concentrating means previously provided at least one of joining portions breaks to produce a starting point of the eutectic reaction.

主权项

1. A joining method comprising:
preparing two members to be joined, each of the two members to be joined having an oxide film disposed over a surface thereof, preparing an insert including an uneven structure for breaking an oxide film, the uneven structure including at least one protrusion having an aspect ratio of greater than or equal to 0.001, disposing the insert between the two members to be joined, applying pressure to the two members to be joined to break the oxide film of the two members to be joined with the uneven structure of the insert, and heating the two members to be joined to initiate a eutectic reaction between the two members to be joined and the insert, such that a eutectic melt produced by the eutectic reaction and the broken oxide film are discharged from between the two members to be joined.
