研究了 200 μm 厚的 Fe-40at.%Al 板材在 973 K 至 1273 K 温度下在 H、S 含量为 0.052-9.7vol% 的 H-2-H2S 混合物中的硫化行为。 Fe-40Al 板材在所有 H2S-H-2 混合物中在低于 1073 K 的温度下均表现出优异的抗硫化性能。 AES 分析表明，这可能是由于硫化过程中 Fe-40Al 板材表面形成了一层薄薄的氧化铝膜所致。在高于1173 K的温度下，Fe-40Al板材在0.052%H2S-H-2混合物中也表现出良好的抗硫化性能。坦佩大鼠里拉的质量增加仅略有增加。与 Fe-200-11Al（at.%）箔相比，Fe-200-11Al 箔在 0.052% H2S-H-2 混合物中即使在 973 K 温度下也会严重硫化，并且随着 H2S 含量和温度的增加，质量增益显着增加。 (C) 2004 Elsevier Ltd. 保留所有权利。
The sulfidation behavior of a 200 mum thick Fe-40at.%Al sheet has been investigated at temperatures between 973 K and 1273 K in H-2-H2S mixtures with H,S contents of 0.052-9.7vol%. The Fe-40Al sheet exhibited excellent sulfidation resistance at temperatures below 1073 K in all the H2S-H-2 mixtures. This may be attributed to the formation of a thin alumina film on the surface of the Fe-40Al sheet during sulfidation, identified by AES analysis. At temperatures higher than 1173 K, the Fe-40Al sheet also exhibited good sulfidation resistance in the 0.052%H2S-H-2, mixture. and there was only a slight increase in mass gain with tempe rat Lire. This compares favorably with Fe-200-11Al (in at.%) foil which was severely sulfidized even at 973 K in the 0.052% H2S-H-2 mixture, and showed markedly increased mass gain with increased H2S content and temperature.
