Abstract
To improve the oxidation protective ability of SiC–MoSi2–ZrB2 coating for carbon/carbon (C/C) composites, pre-oxidation treatment and pack cementation were applied to construct a buffer interface layer between C/C substrate and SiC–MoSi2–ZrB2 coating. The tensile strength increased from 2.29 to 3.35MPa after pre-oxidation treatment, and the mass loss was only 1.91% after oxidation at 1500°C for 30h. Compared with the coated C/C composites without pre-oxidation treatment, after 18 thermal cycles from 1500°C and room temperature, the mass loss was decreased by 30.6%. The improvements of oxidation resistance and mechanical property are primarily attributed to the formation of inlaid interface between the C/C substrate and SiC–MoSi2–ZrB2 coating.
