摘要
To enhance the oxidation resistance of SiC–MoSi2–ZrB2 coating for C/C composites, pre-oxidation treatment and chemical vapor deposition were applied to construct a SiC nanowire-toughened inlaid transition layer between C/C and SiC–MoSi2–ZrB2 coating. The results show that the coating prepared with pre-oxidation and SiC nanowires has better oxidation resistance, which can protect C/C for 124 h at 1773 K in air with the weight loss per unit area of 1.1 mg cm−2. The synergistic effect of the inlaid structure of the transition layer and SiC nanowires plays positive role on alleviating the mismatch of thermal expansion coefficient between C/C and SiC–MoSi2–ZrB2 coating.
