“…Whereas lots of Al element from 2219 aluminum alloy and brazing filler diffused to the side of SiC ceramics and reacted with Ag‐Cu‐Ti contributing to more brittle intermetallic compounds, such as Al 2 Cu (marked by phase C) and Al 3 Ti (marked by phase D), as shown in Figure 5. This situation greatly limited the plastic deformation ability of the brazing seam, which is not conducive to stress release of the joint 21,22,33 . It could be seen from Figure 5A that the thick diffusion and reaction layer near the scratch (marked by an arrow) of SiC matrix.…”

More liquid AgCuTi alloy was provided at the scratch, and the metallurgical bonding of Ag-Cu-Ti and SiC could be promoted by the presence of higher active Ti element.…”

A two-step process involving, the pre-metallization of the SiC ceramic by Ag-Cu-Ti foil and the Al based filler alloy was developed to join 2219 aluminum alloy and the metallized SiC. The composition of metallized SiC layer was investigated. The effect of metallization temperature on the microstructure and mechanical properties of the joint was analyzed. The brazing process showed that Al from the brazing filler and 2219 substrate reacted with Ag-Cu-Ti alloy to form intermetallic compounds. Al 3 Ti, Al 2 Ag and Al 2 Cu were detected in the joint. Ti 5 Si 3 , TiC and Ti 3 SiC 2 compounds were found adjacent to the reaction layer of the Ti and SiC. With increasing of metallization temperature, the shear strength of joint first increased and then decreased. The joint shear strength reached 16.0 MPa when the pre-metallization temperature reached 1000 • C and holding time was 10 min.

“…Many effective solutions have been proposed to solve this problem, such as: solid phase diffusion bonding [10,11], partial transient liquid phase bonding [12], active brazing [13,14] and so on. Among them, active brazing has excellent adaptability in the shape and size of the joint and his process is also fairly simple, which is an attractive industrial application technology [15].…”

The gas-tight joining between yttrium-stabilised semi-closed zirconia ceramic tube and 06Cr19Ni10 stainless steel tube was achieved by using a self-made Ag-27Cu-4Ti paste filler material, where the joint form was an outer sleeve joint. After brazing, the samples were subjected to thermal shock (−50°C to 150°C) and thermal cycling tests (room temperature to 600°C), respectively. The sealing tightness of samples with different assembly clearances was investigated. Microstructure and phase composition of the joint with good performance was analysed. The results showed that the sealing performance of samples with the clearances of 0.03∼0.04 mm was best, and their tightness could still be less than 5 × 10 −10 Pa•m 3 s −1 after a series of heat treatment; microstructure of the joint with good sealing was dense and there were no obvious defects; the joining layer adjacent to ceramic was mainly comprised of three continuous reaction layers, the composition phase of which included Ti 3 Cu 3 O, TiO and ZrTiO 4 .
