Dissimilar material brazing method of porous intermediate layer structure brazing seam
The invention discloses a dissimilar material brazing method of a porous intermediate layer structure brazing seam, relates to the field of welding of materials, and aims to solve the problems that great residual stress can be easily generated by a connector in the existing brazing process of the dissimilar material, the mechanical property of the connector is greatly reduced, even the connected connector is damaged. The method comprises the following steps of grinding and removing impurities on a ceramic matrix composite material and a metal material, then uniformly mixing a nanometer aluminum oxide template with a brazing filler to obtain a composite porous intermediate layer brazing filler, sequentially stacking the ceramic matrix composite material and the metal material, subsequently putting the composite porous intermediate layer brazing filler between the to-be-welded surfaces of the ceramic matrix composite material and the metal material to obtain a to-be-welded part; putting the to-be-welded part in a vacuum brazing furnace, vacuumizing, preserving heat at the high temperature, and finally cooling to the room temperature, thus completing the dissimilar material brazing process of the porous intermediate layer structure brazing seam. The method is suitable for brazing the dissimilar material of the porous intermediate layer structure brazing seam.
