Abstract: Urgent thermal protection needs exist for the new generation of aerospace equipment, and there is an urgent need to develop ultra-high temperature ceramics with excellent thermodynamic, oxidation, and ablation resistance properties. Among them, the carbide ultra-high temperature ceramic system, which has the most outstanding thermal properties, has shortcomings in mechanics and oxidation resistance. Starting from the structure and properties of carbide ultra-high temperature ceramics, this review summarizes the enhancement effects of strengthening-toughening designs, including toughening phase introduction and microstructural bionization, on the mechanical properties. The entropy-enhancing research to modulate its structure and properties is introduced, covering cationic solid solution, anionic modification, and high-entropy design. The main construction methods of carbide ultra-high temperature ceramic thermal protective coatings are sorted out, and the oxidation and ablation resistance properties and mechanisms of the resulting coatings are summarized. Finally, the main development directions of carbide ultra-high temperature ceramics are outlined in terms of material computational design, synergistic enhancement by strengthening-toughening and entropy-enhancing, ablation property and mechanism, and preparation of large-size components and coatings.

Key words: equipment thermal protection, carbide ultra-high temperature ceramics, strengthening-toughening, entropy manipulation, thermal protective coatings
