Abstract
A diffusion bonding method for corrosion resistant materials comprises: disposing an insert material having a melting point of at most 1150 degrees C. and a thickness of 10-80 micrometers between the bonding interfaces of two members to be joined, the insert comprising, by weight %, PA0 Cr: 5-40%, PA0 one or more of Si: at most 8% and B: at most 4%, and PA0 a remainder of at least one of Fe and Ni and incidental impurities; and heating the bonding interfaces of the two members by high-frequency induction heating for at least 120 seconds at a temperature of 1150-1250 degrees C. in an atmosphere containing at most 200 ppm oxygen while applying a pressure of 0.5-2 kgf/mm.sup.2 to the bonding interfaces so as to melt the insert material.
