Abstract
PURPOSE: To enable diffusion joining even in super-heat-resistant alloys, by setting a pair of members to be joined butt to butt with a soft metal layer inserted in the middle, rotating one member with respect to the other member, and keeping the heated pressurized state for a specified period of time.
CONSTITUTION: Soft metal layers 3, 3 of thin pieces of Ni, Cr or the like are formed on the surfaces of grooves 2, 2 of members 1, 1 to be joined (super-heat-resistant alloy). With one of the members 1, 1 secured, while rotating the other member at low speed so that the both joining surfaces on one side may be parallel, pressure is applied so that the soft metal layers 3, 3 may contact with each other, and at the same time the joining part is heated to high temperature by the rotary frictional heat. Thus, the members 1, 1 are joined together through the soft metal layer 3, then the rotation of the one member 1 is stopped. Next, under the specified joining temperature and pressure, the same state is maintained for 5 minutes to 14 hours to promote the diffusion between the soft metal layers and the members being joined, and a boundary layer 5 almost similar to the member being joined is formed in the joining part, and joining is completed.
