Abstract

SiC_f/SiC composites are candidate structural and functional materials for fusion blankets, attractive for their potential application for higher temperature liquid metal blankets compared to the range possible for metallic materials. However, the experimental data on the long term compatibility of SiC_f/SiC composites with high temperature liquid metal is inadequate. To acquire parametric data on the compatibility of NITE SiC_f/SiC composites with a high temperature liquid metal stream, the corrosion behavior was examined in liquid Pb-Li using a rotating disk apparatus. The materials used in this study were exposed to relative flow velocity of ∼10-37 cm/s at 900 °C for 1000 h. Oxidation layers were detected on the matrix and fiber near the surface exposed to liquid Pb-Li at 900 °C for 1000 h. Additional results for shorter exposure times and relationship to flow velocity are discussed.
