| Abstract: | A kind of anti-erosion ZrC/SiC coating for C/C composites was prepared by a two-step method of pack cementation and slurry.The ablation characteristics,phase composition and micro-structure of ZrC/SiC coating were studied by oxyacetylene flame test,XRD and SEM,respectively.The ablation mechanism of the coating was also investigated.It shows that the ZrC/SiC coating combines well with the substrate and has fine thermal-stability.The mass ablation rate of the ZrC/SiC coating is very low.The ablation mechanism... |
