| Abstract Scope |
The development of advanced nuclear systems imposes stringent demands on fuel materials, requiring exceptional high-temperature strength, corrosion resistance, and thermal conductivity. While cermet fuels are promising candidates, their performance is often limited by poor compatibility between ceramic particles and metallic matrix. To enhance compatibility and thermal conductivity, a novel design was developed, consisting of niobium (Nb)-coated ceramic particles embedded in a Nb metallic matrix. The Nb coating was deposited by fluidized-bed chemical vapor deposition (FB-CVD), and the deposition mechanism of Nb coating via FB-CVD was proposed. The consolidation process of Nb-coated ceramic particles in the Nb matrix was achieved by spark plasma sintering. The microstructure and mechanical properties of Nb coating and the pellet were investigated by SEM and nanoindenter. The results proved the effectiveness of Nb coating in preventing ceramic particles from contact and cracking during sintering. |
