摘要: Abstract The corrosion performance of Ni-16%wt.Mo-X%wt.SiC (X = 0.5, 1.5, 2.0, 2.5 and 3.0) alloys prepared via mechanical alloying followed by consolidation using spark plasma sintering (SPS) from pure Ni, Mo SiC powders is investigated. Corrosion testing at 650 °C/200 h in FLiNaK molten salt showed that increasing the volume fraction initial Ni-Mo-SiC powder mixture leads to formation large amount Mo2C precipitates, which readily dissolve into salt. Hence, only resistance NiMo-SiC with a low content (
