چکیده انگلیسی
Nitrogen-modified ZrC-SiC coatings were prepared by thermal evaporation, in situ reaction, and nitriding process, and the microstructure and ablation property of the coatings were studied. The results showed that nitrogen atoms could replace the carbon atoms and fill the vacancies of ZrC. In addition, the interface of the ZrC phase was optimized. The nitrogen atom solid solution was limited on the coating surface, and the interior of the coating was composed of high-melting point ZrC and SiC ceramics. The ablation test showed a reduction in the ablation rate of the coating after nitriding due to the formation of a dense ZrO2 layer.
