Abstract

To improve the high-temperature stability of carbon/carbon (C/C) composites, a LaB ₆ -MoSi ₂ -ZrB ₂ (LMZ) coating was deposited on SiC-encapsulated C/C composites by supersonic atmospheric plasma spraying. The sprayed LMZ coating showed a significant improvement of oxidation and ablation protective abilities relative to MoSi ₂ and ZrB ₂ coatings, which could protect C/C composites for more than 80 h at 1773 K in static air and 60 s above 2000 K under oxyacetylene flame. La and Zr acted as the role in accelerating the liquid phase sintering of SiO ₂ -based oxides, forming a compact Si-Zr-La-O compound scale to enhance the high-temperature stability of LMZ coating.
