The aim of the work has been to study the corrosion resistance of a new low alloyed experimental FeCrAl steel, with the potential use as corrosion barrier in high temperature lead based energy applications. The exposures were conducted in liquid lead at 800 °C and 900 °C, with controlled oxygen environment, for up to 1760 h. The results demonstrate that the new experimental alloy had formed a protective oxide in both exposures, with no indications of lead penetration. The alloy showed better corrosion properties than that of the reference materials: Kanthal APM™, Kanthal APMT™ and AISI 316L. This indicates that the ductile Fe–10Cr–4Al-RE steel can be used as a corrosion barrier in liquid lead based clean energy applications, operating at very high temperatures.

这项工作的目的是研究一种新型的低合金实验性FeCrAl钢的耐腐蚀性，并有可能在高温铅基能源应用中用作腐蚀阻挡层。暴露是在800°C和900°C的液态铅中，在受控的氧气环境下进行的，长达1760 h。结果表明，新的实验合金在两次暴露中均形成了保护性氧化物，没有迹象表明存在铅渗透。该合金显示出比参考材料Kanthal APM™，Kanthal APMT™和AISI 316L更好的腐蚀性能。这表明易延展的Fe-10Cr-4Al-RE钢可以在高温下使用的液态铅基清洁能源应用中用作腐蚀防护层。
