ABSTRACT:
Disclosed is a diffusion bonding method which can be applied to superalloys and comprises forming in advance an alloy layer containing an additional element or elements having a higher diffusion speed than that of the principal constituent element of a base metal and a lower melting point than that of the base metal on the joint surface of the base metal consisting of a heat-resistant superalloy based on Co, Ni, Fe, Ti or the like, and bringing the joint surfaces into contact so as to diffuse B.
