英文摘要	Immersion corrosion tests of TiC0.(8), TiC, TiC-20 vol% SiC, TIC-40 vol% SiC and SiC have been performed in molten FLiNaK salt at 800 degrees C for 25-200 h under argon cover gas. All of these five samples showed small mass loss and relatively good corrosion resistance in molten FLiNaK salt. The corrosion patterns of TiC0.8, TiC, TiC-20 vol% SiC and TiC-40 vol% SiC were inter-granular corrosion, which were attributed to the depletion of Ti along the grain boundaries. SiC exhibited a general corrosion process in which a carbon rich layer formed on the surface, resulting from the depletion of Si. The carbon-rich layer protected SiC against further corrosion, hence lowering the corrosion rate. The corrosion results of TiC-20% SiC and TiC-40% SiC revealed the corrosion resistance of TiC could be improved by adding SiC. And the contribution of SiC to better corrosion resistance has been elucidated. (C) 2017 Elsevier Ltd. All rights reserved.
