Abstract

Al-Si alloy coating was prepared on the surface of SiC coated carbon-carbon composites by slurry method. Microstructure and oxidation resistance of as-prepared SiC/Al-Si multi-layer coating were studied by XRD, SEM, and isothermal oxidation test under 1500°C in air respectively. The results showed that Al_3.21Si_0.47 and a few Al₂O₃ were the main phase of Al-Si outer coating. The thickness of SiC/Al-Si multi-layer coating was about 120 μm and without penetrable cracks. The oxidation resistance of SiC/Al-Si multi-layer coating was obviously better than that of single SiC coating. The mass loss of SiC/Al-Si multi-layer coated carbon-carbon composites was less than 5% (mass fraction) after oxidation for 17h.
