| 英文摘要 | SiCf/SiC composites modified by layered Y2Si2O7 were presented in this research. Layered Y2Si2O7 was transformed from yttrium oxide by chemical vapor infiltration process in SiC fiber preform, in which yttrium oxide was generated by the solution impregnation and pyrolysis method. Oxidation behavior of the layered-Y2Si2O7 modified SiCf/SiC composites was studied in the wet oxygen environment at 1400 degrees C, showing that Y2Si2O7 can concentrate on the oxidation surface to form a protective layer during the oxidation process. The bending strengths of SiCf/SiC composites with one layer or three layers of Y2Si2O7 remain 60.38% and 71.93%, respectively, after the oxidation for 80 h. In contrast, it is only 50.11% for SiCf/SiC composites without Y2Si2O7. Therefore, layered distribution of Y2Si2O7 significantly improves the oxidation resistance of SiCf/SiC composites in wet oxygen environment. |
