The oxidation behaviour of the spring steel 60Si2MnA in atmospheres containing 0–21% (volume per cent) O 2 , < 20 ppm (part per million) to 17%H 2 O, with some containing 8%CO 2 , at 700–1000 °C was investigated. The oxide scale thicknesses formed in both 17%H 2 O–N 2 and dry O 2 -containing atmospheres were less than 6 μm after 20 min of oxidation, significantly smaller than those formed in atmospheres containing both oxygen and water vapour, and the scale structures developed in the three different scenarios were also very different. The scale formed in 17%H 2 O–N 2 contained wustite only, the scale formed in dry O 2 -containing atmospheres comprised primarily hematite and some magnetite, and that in O 2 –H 2 O mixtures developed a multi-layered structure, generally with an innermost Fe 2 SiO 4 + FeO layer, followed by FeO/Fe 3 O 4 /Fe 2 O 3 layers towards the scale surface. A preformed oxide scale and the presence of 8%CO 2 in the atmosphere had little effects on further steel oxidation. The mechanisms of forming different scale structures are discussed.

60Si2MnA 钢在 700–1000 °C 下在含有不同水平的氧气、水蒸气和二氧化碳的气氛中的氧化

弹簧钢 60Si2MnA 在含有 0–21%（体积百分比）O 2 ，​​< 20 ppm（百万分率）至 17%H 2 O，其中一些含有 8%CO 2 的气氛中的氧化行为，温度为 700–1000 ℃进行了研究。氧化 20 分钟后，在 17%H 2 O-N 2 和干燥含 O 2 气氛中形成的氧化皮厚度均小于 6 μm，明显小于在同时含有氧气和水蒸气的气氛中形成的氧化皮厚度，并且在三种不同情景中开发的结构也大不相同。在 17%H 2 O-N 2 中形成的水​​垢仅含有方铁矿，在干燥的含 O 2 气氛中形成的水​​垢主要由赤铁矿和一些磁铁矿组成，在 O 2 -H 2 O 混合物中形成的水​​垢形成多层结构，通常具有最里面的 Fe 2 SiO 4 + FeO 层，随后是朝向鳞片表面的 FeO/Fe 3 O 4 /Fe 2 O 3 层。预先形成的氧化皮和大气中 8%CO 2 的存在对钢的进一步氧化几乎没有影响。讨论了形成不同尺度结构的机制。
