Phys.org  July 3, 2024 Researchers in China prepared the (Hf0.36Zr0.24Ti0.1Sc0.1Y0.1La0.1)C1-δ (HEC) coatings. The HEC possesses higher toughness with a higher Pugh’s ratio of 1.55 in comparison with HfC (1.30). The in-situ formed dense (Hf0.36Zr0.24Ti0.1Sc0.1Y0.1La0.1)O2-δ oxide scale during ablation benefits to improve the anti-ablation performance was attributed to its high structural adaptability with a lattice constant change not exceeding 0.19 % at 2000–2300 °C. According to the researchers the current investigation demonstrated the effectiveness of the inverse theoretical design, providing a novel optimization approach for ablation protection of high-entropy carbide coatings… read more.
