Fabrication of SiC/C Functionally Graded Material

Laboratory of Special Ceramics and P/M, UST Beijing, Beijing 100083, China

摘要: 以經典無限大疊層板理論和熱彈性力學為基礎,通過自行開發的計算機輔助設計系統對SiC/C FGM中的熱應力分布進行了理論分析,得到制備SiC/C的功能梯度材料最佳工藝參數.采用熱壓燒結工藝,在1950℃,25 MPa和保溫1h的條件下制備出了F4和F7兩種無宏觀缺陷的塊體SiC/C功能梯度材料.采用SEM對FGM微觀結構進行了觀察.500℃室溫淬水實驗表明,按最佳參數制備的功能梯度材料F7具有良好的抗熱震性能.

Abstract: The thermal stress in SiC/C FGM in steady temperature field was analyzed based on the classical lamination theory and thermo-elastic mechanics. The optimum composition distribution parameters for fabricating SiC/C FGM were obtained through the above analysis. SiC/C FGM F4 and F7 were fabricated successfully by hot pressing. The microstructure was observed by SEM. Thermal shock resistance of SiC/C FGM was repeatedly tested by quenching from 500℃ into water with room temperature. It has been proved that FGM F7, which was fabricated with the optimized parameters, has better thermal shock resistance.
