摘要

The corrosion behaviours of GH3535 alloy in molten FLiNaK eutectic salt (LiF-NaF-KF: 46.5–11.5–42.0 mol.%) were investigated in the presence and absence of graphite particles by using a static immersion corrosion technique. Results indicated that graphite particles barely affected the corrosion rate of chromium in the subsurface and increased the corrosion loss of GH3535 alloy in molten salt. These seemingly contradictory results were obtained because the introduction of graphite particles into the molten FLiNaK eutectic salt carbonized and corroded molybdenum, which is one of the most stable elements in the Ni-Mo-Cr alloy in molten FLiNaK salt.
