Abstract

Efficient and appropriate composition design of multi-elemental UHTCs for extremely thermal protection is in great demand and promising for carbon-based materials. Based on (Hf-Zr-Ta-Nb)C protective coating system via plasma spraying, the synergistic effects were clarified through several steps: data collection, mechanism analysis, composition optimization and experiment verification. Results showed that, (Hf0.25Zr0.25Ta0.25Nb0.25)C coating exhibited insufficient protective ability (2000 °C, < 120 s), due to the similar content ratio of high-melting-point and low-melting-point phases. The decline of Ta or Nb relative content effectively improved ablation property, attributed to the supporting effect of more retained (Hf, Zr)O2 skeleton phases. After further screening for the proper composition of Hf, Zr, Ta and Nb elements, the (Hf0.45Zr0.45Nb0.1)C protective system was optimized and verified step by step, which delightfully showed long-term ablation property (2000 °C, > 300 s) with nearly zero linear ablation rate.
