| 摘 要： | 利用粉末冶金方法,完成了SiC和C两种难烧结物质的同步烧结,制备出了SiC成分分布从0％～100％的接近理论密度的SiC/C FGM,显微观察显示材料的成分和结构是呈梯度分布的。材料将SiC的良好的耐腐蚀性和石墨的良好的抗热冲击性结合在一起,并具有较高的有效热导和良好的抗热疲劳能力,化学溅射和Tokamak原位等离子体辐照结果显示材料具有良好的耐高温等离子体冲刷性能。

| Abstract: | Simultaneous sintering of SiC and C was completed with the powder metallurgical method, and with which a near dense plasma facing material with 0-100% compositional distributions of SiC-bulk SiC/C FGM was obtained. Well graded composition and structure of that composite were demonstrated by SEM analysis. SiC/C FGM combines the well erosion resistance of SiC and high thermal-shock resistance of graphite, and has the high effective thermal conductivity and thermal fatigue resistance. Chemical sputtering and Takamok irradiation experiments indicate that SiC/C FGM has good high temperature plasma erosion resistance. |
