High-entropy ceramic modification method of ceramic-based composite material matrix and high-entropy modified composite material prepared by high-entropy ceramic modification method
The invention relates to a high-entropy ceramic modification method of a ceramic-based composite material matrix. The method comprises the following steps: placing the ceramic-based composite material matrix in a high-entropy carbide ceramic precursor solution containing Ti, Hf, Nb, Ta and Mo metal elements for dipping; sequentially carrying out curing and high-temperature cracking to obtain a high-entropy ceramic (Ti < x > 1 > Hf < x > 2 > Nb < x > 3 Ta < x > 4 Mo < x > 5) C matrix with a continuous network structure; dipping in a B4C modified polycarbosilane precursor solution; and sequentially carrying out curing and high-temperature cracking to obtain the high-entropy modified ceramic-based composite material. The invention also relates to the high-entropy modified composite material prepared by the method. The high-entropy modified ceramic-based composite material prepared by the method disclosed by the invention has good mechanical properties.
本发明涉及一种陶瓷基复合材料基体的高熵陶瓷改性方法，包括：将陶瓷基复合材料基体置于包含Ti、Hf、Nb、Ta和Mo金属元素的高熵碳化物陶瓷前驱体溶液中进行浸渍；依次进行固化和高温裂解，得到具有连续网络结构的高熵陶瓷(Tix1Hfx2Nbx3Tax4Mox5)C基体；在B4C改性的聚碳硅烷前驱体溶液中浸渍；依次进行固化和高温裂解，得到高熵改性陶瓷基复合材料。本发明还涉及通过上述方法制得的高熵改性复合材料。本发明方法制得的高熵改性陶瓷基复合材料具有良好的力学性能。
