Method for preparing in-situ SiC-high-entropy ceramic anti-ablation composite coating through one-step method
The invention discloses a method for preparing an in-situ SiC-high-entropy ceramic anti-ablation composite coating by a one-step method, the composite coating takes SiC as a transition layer and (Ti Zr Hf Ta) X as a high-entropy ceramic anti-ablation coating, and X is B or C. The composite coating is prepared by sintering by a one-step method, so that the reaction time is greatly shortened; the prepared composite coating has high-temperature ablation resistance and high density, and a new thought is provided for preparation of the high-entropy ceramic ablation-resistant coating.
本发明公开了一种一步法制备原位SiC‑高熵陶瓷抗烧蚀复合涂层的方法，所述复合涂层以SiC为过渡层，以(Ti Zr Hf Ta)X为高熵陶瓷抗烧蚀涂层，X为B或C，所述复合涂层通过一步法烧结制得，大大缩短反应时间，制得的复合涂层具有高温抗烧蚀性能和较高的致密度，为高熵陶瓷抗烧蚀涂层的制备提供了新的思路。
