Abstract

In this study, the high-temperature steam oxidation resistance of alumina-forming ferritic alloys (AFF) alloys was investigated. A dense α-Al₂O₃ film, heterogeneously nucleated beneath pre-formed Fe₂O₃/Cr₂O₃ oxides, effectively suppressed oxygen diffusion into the substrate, resulting in significantly enhanced oxidation resistance compared to commercial austenitic stainless steels (ASS). Upon prolonged exposure at 700 °C in an air-10 % H₂O atmosphere, AFF alloys exhibited minimal weight change and no surface degradation, unlike conventional ASS alloys. These findings offer valuable insights into the design of cost-effective structural materials that require both high corrosion resistance and mechanical performance. Notably, the AFF alloys demonstrate a favorable balance between these physical properties, positioning them as strong candidates for commercialization in advanced energy systems.

含蒸汽气氛中铝形成铁素体合金的高温抗氧化性

本文研究了铝成形铁素体合金（AFF）的高温蒸汽氧化性能。在预先形成的Fe2O3/Cr2O3氧化物下，致密的α-Al2O3薄膜异质成核，有效地抑制了氧气向基体的扩散，与商业奥氏体不锈钢（ASS）相比，显著提高了抗氧化性。在700°C的空气-10 % H2O气氛中长时间暴露后，与传统的ASS合金不同，AFF合金表现出最小的重量变化和表面降解。这些发现为设计既需要高耐腐蚀性又需要高机械性能的具有成本效益的结构材料提供了有价值的见解。值得注意的是，AFF合金在这些物理特性之间表现出良好的平衡，使其成为先进能源系统商业化的有力候选者。
