“…Among the technologies of joining ceramics and metals, brazing is considered to be an efficient, high-quality and simple effective method. 6 Due to the inherent physical and chemical properties of ceramics and metals, there are some basic problems need to be considered. Metal is difficult to wet ceramic because of the different bond-type matching problems between ceramics and metals.…”

ZrB 2 -SiC ceramics and Nb alloy were brazed at 1160°C for 60 min with CoFeNiCrCuTi x high-entropy alloy filler. The influence of Ti content on the interface structure and mechanical properties of ZrB 2 -SiC/Nb joint was systematically studied. It is found that the rich-Ti Laves phase was formed due to the addition of large atomic size Ti fill into the filler alloy or brazing joint, and its content increases with Ti content.The joint brazed by high-entropy alloys filler without Ti can be divided into a toothshaped Cr 2 B reaction layer and a central area composed of a eutectic mixed structure of FCC phase and rich-Nb lamellar Laves phase. Ti and Nb are mutual solid solution elements. The increase of Ti content in the joint makes the FCC phase and the rich-Nb lamellar Laves phase to transform into a big bulk Ti-rich Laves phase and the quadrilateral (Ti, Nb)B phase. The tooth-shaped Cr 2 B was disappeared. The residual stress generated in the joint during the brazing process tends to cause defects such as holes and microcracks in the bulk Ti-rich brittle Laves phase. Therefore, with the addition of Ti, the normal temperature performance of the joint decreases from 216 MPa to 52 MPa. However, with the increase of Ti, the high-temperature mechanical properties of the joint first decrease, and then increase. It was mainly due to the formation of rich-Ti Laves phase and quadrilateral (Ti, Nb)B with excellent high-temperature mechanical properties. When brazing with CoFeNiCrCuTi 1.5 filler, the high-temperature performance of the joint reached 92% of its room temperature performance.

“…Vacuum soldering technology may also be suitable for the fluxless soldering of composites. This issue was studied by the authors of References [21][22][23][24][25]. However, the time required for soldered joint fabrication was on the order of several tens of minutes and, in some cases, hours.…”

The aim of this research is to characterize the soldering alloy Zn6Al6Ag, and to study the ultrasonic soldering of an Al2O3/metal–ceramic composite (Al/Al2O3). Zn6Al6Ag solder presents a quasi-eutectic structure with a melting point around 425 °C. The solder microstructure consists of a (Zn) + (Al) matrix, reinforced with a silver AgZn3 phase. A bond with the metal–ceramic composite was formed due to the dissolution of Al in the liquid Zn solder. The Al2O3 particles were put into motion, and a new composite was formed on the boundary. The Zn6Al6Ag solder also wetted the surface of the Al2O3 ceramic. A decisive effect on bond formation was caused by zinc and aluminum, whose oxides were combined with the oxides of ceramic material during in-air soldering. An adhesive bond was formed. The average joint shear strength of Al2O3/metal–ceramic composite (Al/Al2O3) was found to be 23 MPa.
