Interfacial microstructure and mechanical property of ZrC-SiC ceramic and TiAl joint brazed with Ag Zr active filler metal

Study on brazing sealing and wave transmittance of single crystal Al2O3 microwave window

“…Nevertheless, its inherent brittleness and low thermal conductivity make it challenging to directly connect with structural metals. Brazing is the preferred route for achieving vacuum seals between ceramics and metals due to its low welding temperature, smooth welding joints, minimal deformation of weld parts, simple process, and high production efficiency [ [8] , [9] , [10] , [11] ]. To continuously enhance brazing performance, researchers worldwide have conducted extensive research.…”

“…Liu Guiwu et al employed the Mo–Mn method to braze Al 2 O 3 ceramic and stainless steel, achieving a maximum joint shear strength of 115 MPa [ 13 ]. Shi J et al utilized AgZr filler metal for direct brazing connection and systematically studied the influence of Zr content on the microstructure and properties of brazed joints [ 11 ]. Copper's excellent ductility, thermal conductivity, and solder wetting property, make it possible to select a suitable brazing process to seal the sapphire wafer with Cu and assemble the microwave window of high-power gyrotron using tooling fixtures.…”

Joining Alumina to Titanium Alloys Using Ag-Cu Sputter-Coated Ti Brazing Filler

“…Indeed, due to the inherent differences in physical, thermal and chemical properties between metals and ceramics, it is quite difficult to produce adequate metal/ceramic joints. The application of ultrasonic bonding [6,7], electrical discharge pulse welding [8,9], solid state diffusion bonding [10,11], brazing [12,13], and laser lap joining [14] were reported in the literature for the joining of dissimilar materials. Moreover, some authors have prepared comprehensive reviews covering this field [15,16].…”
