The high-temperature corrosion behavior of anode current collectors in liquid Ag under an oxidizing atmosphere was investigated. The weight gain in oxygen was higher than that of liquid Ag because of the effective barrier formed by Ag-rich layer coated on the corrosion layer. The thickness of the corrosion layer under oxygen was approximately twice that of the layer developed under liquid Ag because of the effective barrier originating from the Ag-rich layer. The corrosion products on the surface of the specimens in both oxygen and liquid Ag were Al2O3 and FeAl2O4 from 24 to 168 h. The surface morphology that was developed on the scale of the corroded layer represented a buckle structure in liquid Ag and a convoluted structure in oxygen, which resulted from the lateral growth of the oxide. This study proved the improved stability and cost-effectiveness of using FeCrAl alloy as a current collector in a solid oxide membrane system.

FeCrAl 阳极集流体在液态 Ag 和 O2 中的高温腐蚀行为比较，用于固体氧化物膜电解工艺

研究了阳极集流体在氧化气氛下在液态银中的高温腐蚀行为。由于富银层覆盖在腐蚀层上形成了有效的屏障，氧气的增重比液态银的增重要高。由于来自富银层的有效阻挡层，氧气下腐蚀层的厚度大约是液态银下腐蚀层厚度的两倍。从 24 小时到 168 小时，试样表面在氧气和液态银中的腐蚀产物为 Al2O3 和 FeAl2O4。在腐蚀层的尺度上形成的表面形貌代表液态银中的弯曲结构和氧中的回旋结构，这是由于氧化物的横向生长造成的。
