The composites were prepared by modifying silicon carbide fiber with particles of zirconium carbide (ZrC) and boron carbide (B 4 C) and incorporating them into a phenolic resin matrix. The influence of ZrC and B 4 C on the mechanical performance of SiC f /phenolic composites after high-temperature pyrolysis was studied through flexural performance test. The results show that the composite material has good thermal stability and high-temperature mechanical properties. After static ablation at 1 400 °C for 15 minutes, the flexural strength of the composite material reaches 286 MPa, which is still 7.3% higher than at room temperature, indicating that the composite material still has good mechanical properties even after heat treatment at 1 400 °C.

The ZrB 2 –BN composite without ZrC impurity was prepared successfully using reactive hot pressing via carbothermal reduction of ZrO 2 with B 4 C, C, and BN powders. The influences of additives and sintering temperature on the phase and microstructure of composites were investigated. The formation reaction of ZrC was inhibited by decreasing the evaporation of intermediate product B 2 O 3 due to forming a SiO 2 –B 2 O 3 eutectic system with the addition of SiO 2 or SiO 2 – CaF 2 . In comparison, SiO 2 –CaF 2 exhibited better inhibition capacity of ZrC. ZrB 2 –BN composite without impure ZrC phase was achieved. In addition, the content of ZrO 2 decreased with increasing sintering temperature, and finally disappeared when sintered at 1800°C. Moreover, the relative density of the ZrB 2 –BN composite reached 96.9%.

The relationship between the interfacial bonding properties and the mechanical properties of carbon fiber reinforced ZrB 2 –ZrC–SiC composites (C f /ZrB 2 –ZrC–SiC) is currently under investigation. In this study, C f /ZrB 2 –ZrC–SiC composites with varying fiber–matrix interfacial bonding properties were prepared using slurry infiltration and in-situ reactive hot pressing. Polydopamine-derived carbon with different thicknesses was employed as the interphase to create various interfacial bonding properties, where interfacial bonding properties were evaluated using the single-fiber push-out method. Results indicated that a uniform and dense ZrB 2 –ZrC–SiC matrix was constructed, and low-porosity composites without fiber degradation were obtained. For composites with a higher interfacial shear strength (ISS) of 342 MPa, flexural strength and fracture toughness were 209 MPa and 7.5 MPa·m 1/2 , respectively. For composites with a lower ISS of 64 MPa, flexural strength and fracture toughness increased by 41% and 13%, with showing non-brittle behavior and work of fracture up to 10 kJ·m 2 . By combining analyses of thermal expansion behavior, residual thermal stresses, and thermal shock properties at ultrahigh temperatures, thermal mismatch and thermal damage can be minimized through the modulation of ISS. This approach is beneficial for optimizing the mechanical properties of fiber-reinforced ceramic composites.

ZrC and TiC are high-temperature materials that can be used in astronautic and aeronautic industries. Titanium (Ti) and zirconium (Zr) belong to adjacent elements of the same IVB family; their similar chemical properties can form a relatively stable crystal structure. Zr x Ti 1-x C composite ceramics doped with Ti were prepared by precursor pyrolysis method. The precursor of aqueous solution systems is more environmentally friendly than in organic systems. The results show that preparing high-purity Zr x Ti 1-x C composite ceramics can be obtained at the Zr: C and Ti: C molar ratio more than 1: 4. The mole number of C is at least four times than the metal ions Zr 4+ or Ti 4+ . The maximum phase transformation temperature is 502.3 °C in Zr 0.25 Ti 0.75 C, which is significantly higher than the initial oxidation temperature 460 °C of ZrC. The result indicates that the Zr x Ti 1-x C composite ceramics reinforced by Ti have better oxidation resistance than pure ZrC ceramics. The crystal structure and bonding properties, electronic characteristics, phonon dispersion spectrum and dynamic stability, mechanical property, and thermodynamic properties of Zr x Ti 1-x C are calculated using first principles showing that Zr 0.25 Ti 0.75 C is the best material.

Lightweight TiC/ZrC ceramic foams were successfully fabricated using a self-foaming method to address thermal-electromagnetic coupling in extremely high-temperature environments. These ceramic foams feature an interconnected pore structure, achieving a porosity of 75.2% and a density of 0.41 g/cm3. The foam demonstrates low thermal conductivity of 0.21 W·m–1·K–1, promising broadband electromagnetic wave absorption with a minimum reflection loss (RLmin) of −33.9 dB and an effective absorption bandwidth (EAB) of 3.7 GHz. Additionally, it exhibits high load-bearing strength of 26 MPa. The exceptional multifunctionality of these ceramic foams is primarily due to their interconnected pore structure and the solid solution strengthening of TiC in ZrC ceramics. Notably, the ceramic foam also shows remarkable high-temperature resilience. After undergoing five thermal cycles at 1600 °C, the material maintains its structural integrity and performance stability, with electromagnetic absorption characteristics dropped to RLmin of −28.7 dB, along with a mechanical strength of 9 MPa.

Chlorogenic acid (CGA), a dietary polyphenol with antioxidant and therapeutic benefits, can be harmful at high concentrations, necessitating sensitive detection in food. This study presents a ZrO 2 -ZrC-doped laser-induced graphene (ZrO 2 -ZrC-LIG) electrode prepared via a one-step laser carbonization of UiO-66/polyimide film. Structural analysis reveals a three-dimensional porous network with uniformly dispersed ZrO 2 and ZrC nanoparticles in graphene, which increases defect density, conductivity and surface area. The optimal conditions of laser-induced parameters such as power and carving depth for the electrode fabrication were selected. Under the optimal conditions, the electro-oxidation of CGA on the ZrO 2 -ZrC-LIG electrode was carefully investigated with electrochemical parameters calculated. The presence of ZrO 2 , ZrC and LIG exhibited an enhancement to the CGA oxidation with a pair of well-define redox peaks appeared, which was attributed to the faster electron transfer, higher electrocatalytic activity and synergistic effects. When integrated with a wireless portable electrochemical workstation, the fabricated sensor shows excellent analytical performance for CGA detection, including a wide linear range (0.1 μM to 1.0 mM), a low detection limit of 33 nM (3σ), along with high selectivity, stability, and reproducibility. When applied to apple and Eucommia ulmoides samples, it achieves the recoveries of 99.26–103.14%, confirming good analytical reliability. This simple and scalable method offers a promising strategy for developing flexible, portable electrochemical sensors for food safety and nutrition monitoring.

A (ZrC/SiC) 3 alternate coating was deposited on sharp leading edge (SLE) C/C composites by chemical vapor deposition (CVD). The ablation behavior was examined via oxyacetylene torch with heat flux of 2.38 MW/m 2 . The results indicated that the alternate coating exhibited great ablation resistance, providing an effective protection for C/C composites. In initial rapid heating stage, the (ZrC/SiC) 3 alternate coating can relieve thermal stress, avoiding the peeling of coating and keeping an intact coating structure. In subsequent ablation, the SiC layers in central region were consumed rapidly, leaving layered interspaces. Three stacked ZrO 2 layers were reserved with the assistance of the release of thermal stress by interspaces, offering a great anti-scouring effect. In transition and border regions, the alternate SiC layers can delay oxygen erosion of inner coating and C/C substrate by the formation of SiO 2 . It is believed that the results would be helpful for the design and application of anti-ablation coatings on SLE C/C composites.

Traditional surface-enhanced Raman scattering (SERS) substrates typically rely on electromagnetic enhancement, which is predominantly generated by noble metal particles. While their practical limitations hinder widespread application. In contrast, semiconductor substrates have garnered increasing attention in the SERS field due to their capacity to address many of the shortcomings associated with noble metal particles. In this study, we investigated the SERS effect and enhancement mechanism of a novel transition metal carbide (ZrC), further enhancing its performance through morphological alterations and element doping. The detection limits for Rhodamine 6G and Methylene blue using the prepared substrate were found to be remarkably low at 1 × 10 -8 M and 1 × 10 -6 M. To elucidate the enhancement mechanism, Density Functional Theory and Finite Element Analysis were employed. These simulations demonstrated that the observed enhancement arises from chemical mechanisms. The charge transfer process between the SERS substrate and the probe molecule resulted in significantly amplified Raman signals.

To enhance the ablation resistance of C/C-HfC-ZrC-SiC composites at temperatures above 2100 °C, a TiC coating was deposited on the surface of the composites by the molten salt method to achieve pore sealing. The influence of this coating on the ablation behavior of the composites was systematically investigated. When exposed to an oxygen-acetylene flame of 2.4 MW/m 2 for 60 s, the mass ablation rate and linear ablation rate of the TiC-coated composite were only 1.12 mg/s and 0.51 μm/s, respectively. Compared with the uncoated samples (1.64 mg/s and 1.05 μm/s), they were reduced by 32% and 51%, respectively. The excellent ablation resistance can be attributed to the preferential oxidation of the TiC coating to form a continuous liquid TiO 2 layer. This liquid layer significantly reduces the surface heat load through evaporation and heat absorption, lowering the surface ablation temperature by approximately 70 °C. Additionally, the liquid TiO 2 penetrates into the interior of the oxide scale through capillary action and reacts with HfO 2 and ZrO 2 in the matrix, promoting in-situ sintering and forming a dense (HfZrTi)O 2 composite oxide scale with a thickness of approximately 100 μm. The synergistic effect of physical sealing and chemical reaction between the coating and the substrate helps to form a robust self-healing oxide scale, providing effective protection under extreme thermal conditions.

Conventional methods like hot pressing (HP) for fabricating SiC-ZrC ceramics typically require high temperatures and external pressure, which can significantly degrade the performance of SiC fibers and restrict the nuclear application of SiC-ZrC composites. In contrast, this work successfully fabricated dense, high-purity SiC-ZrC ceramics with no obvious residual Si using a relatively low-temperature and pressureless RMI method. An obvious correlation between byproduct ZrSi 2 and processing temperature was observed. Notably, significant phase homogeneity differences were observed in the ceramics obtained from pure Si versus Si-Zr alloy infiltration. The low-temperature and pressureless preparation process of the RMI method in this study has promoted the application of SiC-ZrC ceramics as a modified matrix in SiC f /SiC composites for accident-tolerant fuel (ATF) cladding.

The damage mechanism of carbon fiber and fiber-ceramic interface of C f /ZrC-SiC were investigated and revealed. The chemical reactions of C with ZrO 2 and SiO 2 impurities during the sintering resulted in the surface and grain etching of fiber. The ZrC-SiC ceramics diffused into interface to form a strong bonding under high temperature and press, leading to a failure of stress release and guiding the crack propagation direct across fiber. Both consequently impeded the fiber pull-out and bridging. By obvious contrast, the chemical etching of fiber was effectively inhibited utilizing PyC coating as transition layer, and the strong bonding of fiber with ceramic was relieved at the same time replaced by a relatively weak bonding. As a result, the fiber pull-out and fiber bridging were boosted with a longer length more than 50 µm, over 2 times of uncoated composite, accompanied with obvious crack branching and deflection, together resulting in a graceful mechanical feedback with 2.5 times of work of fracture and improved fracture toughness . This work not only revealed the microstructure forms and inherent mechanism on structure damage of carbon fiber, but also offered an effective method of protecting fiber and tailoring the interface bonding, thereby guiding the design of C f /ZrC-SiC with graceful mechanical performance.

UHTCs are expected to be widely used in the aerospace industry due to their excellent ablation resistance. Currently, the low-temperature densification technology for 3D carbon fibre reinforced UHTCs is relatively scarce, meanwhile the long-term and high-temperature ablation-resistant materials still require further development. Herein, combining with reactive hot pressing at 1800 ℃, the highly dense 3D C f /ZrC-SiC composites were innovatively prepared through cyclic infiltration of slurry into 3D carbon fibre preform. The 3D C f /ZrC-SiC exhibited an excellent ablation resistance under a heat flux of 8.9 MW/m². By regulating the ratio of in situ phases ZrC and SiC, 3D C f /ZrC-SiC had an optimal mass ablation rate of only 0.75 mg/s and an optimal linear ablation rate of only -0.20 μm/s during the ablation process. The excellent ablation resistance was attributed to the formation of a dense ablation layer, which effectively inhibited the matrix from further ablation.
