摘要:
A liquid phase diffusion bonding method using an insert material such as B,C,Si and Hf having a high diffusivity and a melting point higher than that of the base metal is disclosed. During the bonding, the insert material is not melted, but the insert material and the base metal are reacted with each other in such a manner that the diffusion bonding can be carried out under a non-oxidizing atmosphere at a temperature lower than the melting point of the insert material.
