specific Embodiment approach 1
[0019] Specific embodiment one: the soft composite middle layer brazing filler metal of this embodiment is made up of upper layer brazing filler metal, soft middle layer and lower layer brazing filler metal; Wherein the upper layer brazing filler metal is Ag-Cu-Ti brazing filler metal foil; Soft middle layer is Cu Foil, Ni foil or Nb foil; the lower layer of solder is Ag-Cu solder foil.
[0020] This embodiment provides a soft composite interlayer brazing filler metal, which uses the soft composite interlayer to suppress the formation of brittle compounds in ceramic and metal brazing joints. On the basis of not changing the composition of the original commercial solder, the composite intermediate layer brazing filler metal relieves the residual stress of the joint through the addition of the soft intermediate layer, improves the strength of the joint, and increases the shear strength of the joint by 30-109%.
specific Embodiment approach 2
[0021] Embodiment 2: This embodiment differs from Embodiment 1 in that: the thickness of the upper layer of solder is 50-200 μm; the thickness of the soft middle layer is 20-400 μm; the thickness of the lower layer of solder is 50-200 μm. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0022] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the mass purity of the Cu foil, Ni foil or Nb foil is >98%. Others are the same as in the first or second embodiment.
