“…SiC ceramic has excellent mechanical properties, high temperature oxidation resistance, small thermal expansion coefficient and thermal stability. [1][2][3] As a nuclear fuel cladding material, SiC ceramic has sufficient strength, tightness and corrosion resistance, and can prevent the overow of ssion products effectively. 4,5 At the same time, the SiC ceramic material can reduce the risk of hydrogen production by thousands of times, and provide protection similar to zirconium alloys for nuclear fuel.…”

“…The joining in this process occurs by deformation of the surface asperities to develop larger contact between the mating surfaces followed by diffusion of atoms in contact via grain boundaries. The diffusion joining method provides a reliable and high‐temperature resistant joint for SiC‐based materials with different interlayers 15,16 . Most of these diffusion joining technologies are based on hot‐pressing at high temperatures and higher holding time (>1 h) to allow sufficient reaction between the substrate and interlayer.…”

The application of ultra‐high‐temperature ceramics (UHTCs) demands effective ways of joining in overcoming the problems associated with the fabrication of complex‐shaped components. In this study, we choose to investigate a new method of rapidly joining pre‐sintered TaC and HfC ceramics without any filler material using the spark plasma sintering (SPS) technique. A well‐bonded TaC–HfC interface was observed with no apparent cracking and porosity at the joint. The joining mechanisms were predominantly driven by solid‐state diffusion and localized plastic deformation. The nanomechanical properties of the TaC‐HfC joint are better than the HfC while comparable to that of the TaC. High‐load indentation (up to 200 N) results suggest that the TaC–HfC interface is stronger than the parent UHTCs with no crack propagating at the interface. Upon comparison with the parent UHTCs, the damaged area and the average crack length at the interface, reduced up to ~94% and ~56%, respectively. This study shows that the SPS technique can also apply to joining other UHTCs without any filler, resulting in the new field of developing complex components for the thermal protection system (TPS).

“…Silicon carbide (SiC) ceramic, as a kind of the modern ceramic materials, has a series of excellent properties, such as high-temperature resistance, corrosion resistance, high modulus and so on, which has been widely used in rocket engines, space mirrors in the aerospace field, high-temperature components for energy exchange in chemical reaction containers, etc. [1][2][3][4]. In view of the most serious damage and large amount of radioactive release caused by hydrogen explosion in Fukushima nuclear power plant accident in Japan, SiC ceramic matrix fuel cladding materials can reduce the risk of hydrogen production by several thousand times, and provide similar protection for nuclear fuel with zirconium alloy, indicating that SiC ceramic also have advanced application potential in the field of nuclear energy, which was tested by professor Kazimi team from Massachusetts Institute of Technology (MIT) [5,6].…”

The microstructure and mechanical properties of brazing SiC ceramic with Zr-Cu filler metal under different brazing parameters (brazing temperature, holding time) were investigated. The phase of the joint reaction interface between Zr-Cu filler metal and SiC ceramic was characterized by XRD, the microstructure and fracture morphology of the brazing SiC ceramic joint were analyzed by SEM with EDS, and the strength of the joint was evaluated by compression shear test. The results show that the brazing join between SiC ceramic and Zr-Cu filler metal can be realized at the brazing temperature of 1100 °C~1300 °C, and the main products of interface reaction are ZrC and Zr2Si. The shear strength of the joint increases with the brazing temperature, and reaches the highest at 1200 °C. The thickness of interface reaction layer increases with the increase of holding time at brazing temperature of 1200 °C. Thickness of the interface reaction layer is 2.9 μm when the joint is holding for 20 min, and the maximum shear strength of the corresponding brazed SiC ceramic joint is 57 MPa.
