Processing and Characterization of Graded SiC/C Plasma Facing Composite
梯度复合SiC/C面向等离子体材料的制备与表征

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.
