Long-term ablation behavior of Al 4 SiC 4 -YB 4 modified C f /ZrB 2 -SiC composites was characterized by air plasma torch at 2600 °C for 300 s. The phase composition and the microstructure evolution of the composites were investigated. The addition of YB 4 promotes the formation of nano t- Zr 0.92 Y 0.08 O 1.96 crystals, decreasing the phase transition stress in the oxide layer and reducing the volatilization of the glassy phase . However, the addition of Al 4 SiC 4 reduces the melting point of Zr-based oxides and the viscosity of the oxide layer. Therefore, the air plasma torch blows the oxide layer away, leading to the increase of linear recession rate.

A novel design of a multi-layered joint architecture, characterized by the controllable spatial distribution of ceramic reinforcements, was obtained, when brazing ZrB 2 -SiC ceramics and Ti-6Al-4 V reinforced by TiB whiskers with AgCu filler. To induce SiC reinforcements to cluster together, within the center of the filler and especially away from the ZrB 2 -SiC, SiC was added into joint, in the form of a SiC interlayer featuring a 3D-bridged network structure with continuous micro-channels infiltrated by capillary force by liquid filler during brazing. Different SiC particles were connected together, by micro-bridges being not destroyed during brazing. The layer rich in SiC could reduce thermal expansion mismatch between different substrates, the AgCu next to the ZrB 2 -SiC could relax the strain energy by high plastic deformation. Compared to joint brazed with single AgCu, joint strain energy decreased from 10.8 × 10 −6 J to 8.6 × 10 −6 J, accordingly joint shear strength increased from ∼5.4 MPa to ∼41.2 MPa.

ZrB 2 -based ceramic composites were prepared by spark plasma sintering using ZrB 2 powder prepared by molten salt method as raw material and SiC and nano-graphite as additives. The effects of nano-graphite addition on the physical properties and oxidation resistance of ZrB 2 -based ceramic samples were investigated. The results show that the addition of an appropriate amount of nano-graphite can effectively improve the density of ZrB 2 -based ceramic composites and improve the physical properties of the materials. The flexural strength of the ceramic sample with 8 vol.% nano-graphite reached 418.54 MPa, which was 53.14% higher than that of ZrB 2 –SiC ceramic material (273.31 MPa), and its oxidation resistance was also significantly improved. It demonstrats that the addition of an appropriate amount of nano-graphite can effectively improve the physical properties and oxidation resistance of ZrB 2 –SiC ceramic composites. Via prolonging its service life in application and promoting the development of ZrB 2 -based ceramic composites, it is of great significance for clean steel smelting.

In this work, YB 4 -CrSi 2 surface-modified C f /ZrB 2 -SiC composites were fabricated by a slurry coating method. The cyclic ablation resistance of the composites was studied at 2600 °C for 300 s using an air plasma test. The ablation mechanisms of the composites were discussed. The Y 3+ can prevent the phase transition of the ZrO 2 and increase the structural stability of the oxide layer. But the oxide layer cannot prevent the inward O penetration resulting from the forming of Zr 0.9 Y 0.1 O 1.95 grains with abundant oxygen vacancy. After the modification of CrSi 2 , the size of Zr 0.9 Y 0.1 O 1.95 grains can be reduced to nano scale. The adequate SiO 2 glassy phase with the uniform distribution of the Zr 0.9 Y 0.1 O 1.95 nano grains can prevent the O penetration effectively and reduce the mass recession rate of the composites.

Reactive hot pressing technology facilitates the rapid densification and sintering of UHTC-based composites, presenting significant potential for applications in the aerospace field. However, challenges persist in achieving uniform dispersion of fibers and lowering the densification temperature required for optimal consolidation. In this work, the ZrSi 2 , B 4 C and active carbon were used as the raw materials, and the 3D C f /ZrB 2 -SiC composite with an open porosity of 0.91% were successfully fabricated through the slurry impregnation-drying cycles followed by a reactive hot pressing at 1800 °C. The microstructure evolution and high-temperature mechanical properties were also systematically investigated. The microstructure analysis found that the in situ reaction of ZrSi 2 , B 4 C and active carbon during sintering led to the formation of ZrB 2 -SiC ceramic matrix and effectively promoted densification. The 3D C f /ZrB 2 -SiC composite exhibited an average flexural strength of 232.9 MPa at RT, retaining a value of 112.1 MPa at 1200 °C.

To reduce the oxidation damage during the initial active oxidation stage of ZrB 2 -SiC coating, this paper employed a slurry-brushing method to prepare a self-healing Zr-Si-B-O biomimetic glass film on the surface of the ZrB 2 -SiC coating. Furthermore, the oxidation resistance behavior of biomimetic glass films with varying ZrO 2 contents was investigated. Experimental results indicate that the Zr-Si-B-O biomimetic glass film can significantly reduce the oxidation weight gain of ZrB 2 -SiC coating. The biomimetic glass film sample with 70 wt% ZrO 2 exhibits the best oxidation protection effect. After oxidation treatment in the temperature range of 600-1600 °C, the weight gain is only 0.081 × 10 −2 g cm −2 , which is 95.35% lower than that of the sample without the biomimetic glass film; after oxidation at 1700 °C, the final protection efficiency and average carbon loss rate reach the optimal values of 99.97% and 0.34 × 10 −6 g cm −2 s −1 , respectively, and the average oxygen permeability is only 0.35%. The presence of Zr-Si-B-O biomimetic glass film can significantly reduce the oxidation activity and improve the oxidation resistance of the coating. This is attributed to the pre-introduction of a flowable and self-healing glass on the coating surface, which prevented the intense oxidation of the coating at the initial stage.

The microstructure evolution of rod-shaped ZrB 2 in situ synthesis of ZrB 2 -SiC composite powder was studied under different heat treatment. TG-DSC, XRD , SEM, EDS, TEM, and HRTEM were used to describe the preparation, phase composition and morphology of rod-shaped ZrB 2 . As a result, tiny ZrB 2 rod grew out of the liquid phase and adopts a layered growth process. As the rod grew in the longitudinal and transverse directions, the surrounding liquid phase was consumed, and the adjacent rods began to grow in parallel or cross grow to form multiple structures.

Balancing light weight, thermal stability, and strong Electromagnetic (EM) wave absorption remains a key challenge for advanced high-temperature absorbers. While conventional electrospinning (ESP) can produce nanofibers, its low throughput and tendency to form densely packed 2D films limit the construction of the bulk 3D porous networks required for optimal impedance matching and multiple scattering. Herein, a flexible ZrB 2 /SiC nanocomposite fiber mat was fabricated via an electro-blown spinning (EBS) strategy, which integrates electric field force and high-speed airflow to achieve high-efficiency, large-scale production of 3D interconnected architectures. The introduction of ZrB 2 nanoparticles builds abundant heterogeneous interfaces and enhances interfacial polarization as well as conductive loss. Meanwhile, the EBS process produces ultralight, 3D porous networks with excellent impedance matching and mechanical adaptability. Consequently, the nanocomposite exhibits outstanding integrated performance with an ultralow density of 0.022 g cm −3 , representing a 75% reduction in density compared to conventional ESP-derived samples (0.083 g cm −3 ). Moreover, the nanocomposite demonstrates excellent microwave absorption capabilities, achieving a RL min of −68.8 dB and an effective absorption bandwidth of 6.5 GHz at a thickness of 1.7 mm. Furthermore, the nanocomposite mats exhibit excellent mechanical flexibility and low thermal conductivity (0.021 W/m·K), offering a robust and scalable route for multifunctional ceramic-based absorbers.

s Continuous carbon fiber-toughened ZrB 2 -SiC ceramics matrix composites (C f /ZrB 2 -SiC), which combine the high strength of carbon fiber needled preforms with the ultra-high-temperature ablation resistance of ZrB 2 -SiC ceramics, exhibit complex responses in the extreme thermo-mechanical-oxygen coupling environments. The fracture behavior and damage mechanisms of the lightweight C f /ZrB 2 -SiC composites were investigated by the thermo-mechanical-oxygen coupling tensile tests. The residual strength after oxidation was found to be synergistically reduced by temperature and pre-tensile load, with a linear negative correlation between pre-tensile stress and residual strength. The needled fibers improve the interlaminar toughness but introduce the localized porosity that accelerates oxygen diffusion and oxidative damage. Under air oxidation at 1100°C, pre-tensile stress reopens self-healing microcracks, transforming the oxidation kinetics from diffusion-controlled to reaction-controlled regimes. This study can provide an experimental basis and practical guidance for the design of needled fiber preforms to balance oxidation resistance and mechanical properties.

To address the issues of long preparation cycle and high cost in fiber-reinforced ultra-high temperature ceramic matrix composites, C f /ZrB 2 -SiC composite was prepared by slurry injection combined with reactive melt infiltration (RMI). The dispersion and rheological behavior of slurries with different compositions were investigated, as well as the impact of various slurries and injection methods on the three-dimensional filling of porous C f /ZrB 2 -C composite. The porosity of porous C f /ZrB 2 -C composite was 24.4–37.2% and the bulk density was 1.70–2.36 g/cm 3 after injection and infiltration. The porous C f /ZrB 2 -C composite obtained by double-sided injection has uniform distribution of ceramic phase, and the bulk density and open porosity are 2.36 g/cm 3 and 24.4% when the ceramic content is 70 wt.% in slurry. Additionally, the volume filling rate has increased by 32% compared to single-injection. After 1 h of silicon infiltration at 1450°C, the flexural strength and fracture toughness of the C f /ZrB 2 -SiC composite were 188.8 MPa and 5.51 MPa·m 1/2 . Compared with other RMI processes, this study showed no significant damage to carbon fibers after low-temperature silicon infiltration, and has certain advantages in mechanical properties. It achieved uniform high solid-content ZrB 2 incorporation and rapid densification, enabling cost-effective short-cycle fabrication of C f /ZrB 2 -SiC composite.

Carbon fiber reinforced ultra-high temperature ceramic matrix composites (C f /UHTCMCs) are considered ideal materials for thermal protection components in hypersonic vehicles due to their outstanding overall performance. However, the existing fabrication techniques for C f /UHTCMCs face significant engineering challenges, including high raw material costs and complex processing methods. Here we propose a cost-effective fabrication strategy. This approach ensures the oxidation and ablation resistance of the material by incorporating sufficient ZrB 2 and SiC, followed by filling the remaining pores in the composite with in-situ derived pyrolytic carbon from furfuryl ketone resin, which significantly reduces fabrication costs and enables rapid densification. The C f /ZrB 2 -SiC-C composites produced by this strategy exhibit a flexural strength of 468 ± 18 MPa and a fracture toughness of 18.23 ± 1.14 MPa m 1/2 . Furthermore, the composites remain non-ablative when exposed to temperatures of 2300 °C for extended periods, with a mass ablation rate of only 4.14 × 10 −6 g/(mm 2 ·s) after 400 s of testing. This strategy offers significant design versatility and can be applied to various ultra-high temperature ceramic systems, offering a novel and cost-effective approach to the development of thermal protection materials for hypersonic vehicles.

To address the poor mechanical properties of hexagonal boron nitride (h-BN) ceramics while maintaining their high directional thermal conduction performance, this study proposes a laminated structure design using h-BN as the soft, thermally anisotropic matrix layer and ZrB 2 -SiC as the hard reinforcing layer. h-BN/ZrB 2 -SiC laminated composite ceramics with different layer thickness ratios were fabricated via tape casting and hot-pressing. The h-BN grains maintain strong preferred orientation with their c-axes aligned parallel to the sintering pressure, even after introducing ZrB 2 -SiC layers. At an optimal layer thickness ratio of 1:1, the laminated ceramic achieves the best mechanical performance, with a flexural strength of 169.09 ± 18.67 MPa and a fracture toughness of 8.32 ± 0.97 MPa·m 1/2 , representing increases of 74% and 169%, respectively, compared with tape casted monolithic h-BN ceramics. These enhancements arise from synergistic toughening mechanisms including crack deflection, branching and delamination. Moreover, the laminated structure preserves strong anisotropic thermal conduction. At a layer thickness ratio of 2:1, the composite exhibits the highest thermal conduction anisotropy, with a temperature difference of ∼5 °C between in-plane and through-plane directions at 150 °C. These results demonstrate that the h-BN/ZrB 2 -SiC laminated architecture effectively combines high directional heat transfer with significantly improved mechanical properties, offering a promising solution for advanced thermal management in microelectronics and high-power devices.
