Abstract：
The corrosion behavior of 20G and TP347H materials was investigated in molten LiCl-NaCl-KCl salt. The corrosion rates of these materials in molten chloride salt are high and are strongly affected by the alloying surface oxide formation. The 20G shows uniform surface corrosion with almost no protective oxide formation on the surface. In contrast, the austenitic steel TP347H exhibits better corrosion resistance in molten chloride salts due to its high Cr content. Owing to the highly corrosive nature of molten chloride salts, the Cl- in molten salt could react with oxides and alloy, inducing intergranular corrosion of austenitic steel in molten chloride salt environments.
摘要：
研究了20G和TP347H材料在熔融LiCl-NaCl-KCl盐中的腐蚀行为。这些材料在熔融氯化物盐中的腐蚀速率很高，并且受到合金化表面氧化物形成的强烈影响。20G显示出均匀的表面腐蚀,在表面上几乎没有形成保护性氧化物。相比之下,奥氏体钢TP347H由于其高Cr含量而在熔融氯化物盐中表现出更好的耐腐蚀性。由于熔融氯化物盐的高腐蚀性，熔盐中的Cl-可以与氧化物和合金反应，在熔融氯化物盐环境中诱导奥氏体钢的晶间腐蚀。
