Abstract
To enhance the cyclic ablation performance of SiC coating from1750 °C to room temperature under vertical oxyacetylene torch, interface design and HfC additive were combined. A porous surface of C/C composites was firstly constructed by oxyacetylene flame so as to form an inlaid interface after the pack cementation preparation of HfC-SiC coating. After 8 ablation thermal cycles, the mass loss per unit area of the HfC-SiC coating was only 36.47 mg cmâ2. Based on thermogravimetric analysis, adhesive strength and thermal expansion test, effect of the inlaid interface on oxidation as well as ablation performance of the HfC-SiC coating was discussed.
