Abstract

To improve the oxidation protective ability of carbon–bonded carbon fiber (CBCF) composites. A multilayer coating containing ZrB₂, MoSi₂, SiCw and borosilicate glass was prepared on ZrB₂-modified carbon–bonded carbon fiber composites (CBCFs/ZrB₂) by a trace oxygen sintering method and a pre-oxidation process. The microstructure, surface emissivity and ablation resistance of the multilayer coating were studied. The coating containing dense surface layer and porous inner layer was obtained. The total emissivity of the coating in the wavelength range of 6–16 μm at 300, 500 and 800 °C was 0.72, 0.73 and 0.78, respectively. The prepared multilayer coating exhibited excellent ablation resistance for 1000 s under simulated atmospheric re-entry conditions by high frequency plasma wind tunnel test with a heat flux of 131.8 W/cm²and stagnation pressure of 2.7 KPa.
