High-entropy carbide SiC gradient composite anti-ablation coating and preparation method thereof
The invention discloses a high-entropy carbide SiC gradient composite anti-ablation coating and a preparation method thereof.The coating comprises high-entropy carbide and silicon carbide, and the high-entropy carbide is prepared from a raw material A containing a Ti source, a raw material B containing a Zr source, a raw material C containing an Hf source and a raw material D containing a Ta source. According to the coating, gradient or uniform distribution of the high-entropy carbide and the silicon carbide is achieved by regulating and controlling the proportion of the high-entropy carbide and the silicon carbide, and the average oxidation rate of the prepared coating at the temperature of 1600 DEG C reaches 0.005 g.cm <-2 >. H <-1 > to 0.01 g.cm <-2 >. H <-1 >.
