Strong-bonding anti-ablation high-entropy ceramic coating and preparation method thereof
The invention discloses a strong-bonding anti-ablation high-entropy ceramic coating and a preparation method thereof.The high-entropy ceramic coating is prepared by mixing TiC, ZrC, HfC and TaC and conducting ball milling, pressing and sintering, TiC, ZrC, HfC and TaC have extremely high melting points and thermal stability, and meanwhile TiC, ZrC, HfC and TaC are good in compatibility. Particularly, the high-entropy ceramic coating is prepared by adopting spark plasma sintering, the period is short, the binding force between the prepared high-entropy ceramic coating and a carbon matrix is very strong, and the problems of large difference between interfacial compatibility and thermal expansion coefficient and the like are expected to be thoroughly solved.
本发明公开了一种强结合抗烧蚀高熵陶瓷涂层及其制备方法，将TiC、ZrC、HfC和TaC混合，经球磨、压制和烧结制得所述高熵陶瓷涂层，所述TiC、ZrC、HfC和TaC具有极高的熔点和热稳定性，同时TiC、ZrC、HfC和TaC之间的良好的相容性。特别是采用放电等离子烧结制备所述高熵陶瓷涂层，周期短，且制得的高熵陶瓷涂层与碳基体之间的结合力非常强，有望彻底解决界面相容性与热膨胀系数差异大等问题。
