چکیده انگلیسی
Fine-grained and high-density SiC coating was fabricated on carbon materials by incorporating SiC nanowires during the pressure-less reactive sintering for the first time. The grain size, relative density, and fracture toughness of the as-fabricated coating are 1.5â¯Â±â¯0.6â¯Î¼m, 95%, and 5.03â¯Â±â¯0.73â¯MPaâ¯m1/2, respectively, resulting in a good oxidation protective ability, which can efficiently protect carbon materials from oxidation at 900â¯Â°C for more than 70â¯h or at 1500â¯Â°C for more than 90â¯h. The formation of such microstructure may be associated to the increasing nucleation rate resulting from the microstructure evolution and phase transformation of SiC nanowires during the sintering process.
