Abstract 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.

熔融LiF-NaF-KF共晶盐中石墨颗粒对GH3535合金腐蚀行为的影响

摘要 GH3535 合金在熔融 FLiNaK 共晶盐 (LiF-NaF-KF: 46.5–11.5–42.0 mol.%) 中的腐蚀行为通过使用静态浸入腐蚀技术在石墨颗粒存在和不存在的情况下进行了研究。结果表明，石墨颗粒对亚表层铬的腐蚀速率几乎没有影响，并增加了GH3535合金在熔盐中的腐蚀损失。这些看似矛盾的结果是因为将石墨颗粒引入熔融 FLiNaK 共晶盐中会碳化和腐蚀钼，钼是熔融 FLiNaK 盐中 Ni-Mo-Cr 合金中最稳定的元素之一。
