Micro/nano multiscale reinforcing strategies toward extreme high-temperature applications: Take carbon/carbon composites and their coatings as the examples

Qiangang Fu et al.

Summary: Carbon fiber reinforced carbon composites (C/Cs) are promising high-temperature materials, but they are prone to destructive oxidation at elevated temperatures. Matrix modification and coating technologies are not sufficient due to brittleness of ceramics and other inherent issues. Micro/nano multiscale reinforcing strategies have been developed in the past two decades to fabricate C/Cs with high strength and excellent high-temperature stability.

Ablation behavior of single and alternate multilayered ZrC-SiC coatings under oxyacetylene torch

Guanghui Feng et al.

Summary: The investigation focused on the ablation behavior and thermal stress of monolayered ZrC-SiC coatings with different SiC amounts. An alternate coating with 4 sublayers containing 10 and 70 vol.% SiC was applied on SiC-coated C/C composites. Ablation tests under oxyacetylene torch showed that the alternate coating provided superior ablation properties by enduring mechanical denudation and hindering oxygen transport inward during ablation.

Optimal preparation of high-entropy boride-silicon carbide ceramics

Yan Zhang et al.

Summary: This study examined the effects of using borothermal and boro/carbothermal reduction methods in fabricating high-entropy boride-silicon carbide (HEB-SiC) ceramics. It was found that spark plasma sintering at 2000 degrees C could achieve HEB-SiC ceramics with > 98% theoretical density, and the addition of SiC resulted in slight coarsening of the microstructure. The results suggested that the choice of powder processing method and the inclusion of SiC phase could optimize the preparation of high-entropy boride-based ceramics.

Summary: Textured high-entropy boride ceramics were successfully fabricated for the first time using spark plasma sintering, with nearly single phase formation. The c-axis of boride grains aligned parallel to the SPS pressing direction, with grains growing along the a,b-axis to form platelet-like morphology. The ceramics exhibited a remarkably high Vickers' hardness and improved fracture toughness on the surface perpendicular to the SPS pressing direction due to oriented elongated grains.

Summary: A new Al2O3/(NbTaMoW)C composite was designed in this study using an in-situ exothermic reaction method. The resulting composite exhibited a unique microstructure with high entropy carbide and Al2O3 phases, and a noncoherent interface between the two phases which enhanced the mechanical properties such as flexural strength and fracture toughness. The presence of an interlocking structure and inhomogeneous temperature distribution contributed to the improved properties of the composites compared to traditional (NbTaMoW)C materials.

Ablation behavior of (Zr,Ta)B2-SiC coating on carbon/carbon composites at 2300 °C

Kai Tong et al.

Summary: The Zr-Ta-B-SiC multiphase coating prepared on carbon/carbon composites exhibited excellent ablation resistance at high temperatures, with the key antiablative component being the (Zr,Ta)B-2 solid solution. The micromorphology and distribution of Zr-Ta-O in the coating played a vital role in protective layer evolution and ablation performance, with a coating containing around 30% Ta beneficial for stabilizing the t-ZrO2 phase and alleviating volume change. The formation of a thermal barrier and low volatility of the Zr-Ta-O layer were responsible for the coating's outstanding ablation resistance.

Summary: The study investigated the oxidation behavior of multi-component non-stoichiometric (Zr, Hf, Ti)C-x carbide solid solution and found that the composition of metallic atoms plays a crucial role in determining the oxidation resistance. The presence of a high Hf content was beneficial in forming an amorphous Zr-Hf-Ti-C-O oxycarbide layer as an oxygen barrier, while equiatomic ratios of metallic atoms reduced the growth rate of (Zr, Hf, Ti)O-2 oxide, improving the oxidation activation energy of (Zr, Hf, Ti)C-x.
