Ablation behavior of(ZrC/SiC)3 alternate coating prepared on sharp leading edge C/C composites by CVD
文献摘要：
A(ZrC/SiC)3 alternate coating was deposited on sharp leading edge(SLE)C/C composites by chemical va-por deposition(CVD).The ablation behavior was examined via oxyacetylene torch with heat flux of 2.38 MW/m2.The results indicated that the alternate coating exhibited great ablation resistance,providing an effective protection for C/C composites.In initial rapid heating stage,the(ZrC/SiC)3 alternate coating can relieve thermal stress,avoiding the peeling of coating and keeping an intact coating structure.In subse-quent ablation,the SiC layers in central region were consumed rapidly,leaving layered interspaces.Three stacked ZrO2 layers were reserved with the assistance of the release of thermal stress by interspaces,offering a great anti-scouring effect.In transition and border regions,the alternate SiC layers can delay oxygen erosion of inner coating and C/C substrate by the formation of SiO2.It is believed that the results would be helpful for the design and application of anti-ablation coatings on SLE C/C composites.
