Abstract The cyclic hot corrosion behaviors of TiAl based intermetallics were studied in two different molten salts consisting of % wt. Na2SO4-25NaCl and Na2SO4-25K2SO4 at 800 and 900 °C for 180 h, respectively. The aim of the study is to elucidate the effect of alloying elements on hot corrosion phenomena in the corrosive molten salt mixture. Corrosion kinetics revealed the Mo-added samples exhibit poor corrosion resistance in both corrosive salt mixture. It has been found that the NaCl-containing salt mixture clearly influence the extent of degradation due to the self-sustaining reaction mechanism.

两种不同熔盐混合物对电阻烧结TiAl基金属间化合物的腐蚀行为

摘要 在两种不同的熔盐中研究了 TiAl 基金属间化合物的循环热腐蚀行为。Na2SO4-25NaCl 和 Na2SO4-25K2SO4 在 800 和 900 °C 下分别放置 180 小时。该研究的目的是阐明合金元素对腐蚀性熔盐混合物中的热腐蚀现象的影响。腐蚀动力学表明添加 Mo 的样品在两种腐蚀性盐混合物中都表现出较差的耐腐蚀性。已经发现，由于自持反应机制，含 NaCl 的盐混合物明显影响降解程度。
