基本上所有在高温下耐腐蚀的合金和涂层都需要通过称为选择性氧化的过程形成保护性（缓慢生长和粘附）氧化物层。多年来，人们对暴露在纯氧或空气中的这一过程有了基本的了解。然而，大多数应用中的大气中含有大量的水蒸气，这会极大地改变保护性氧化物的行为。氧燃料燃烧系统的发展，其中化石燃料在再循环烟道气和氧气的混合物中而不是在空气中燃烧，引起了人们对水蒸气和蒸汽对合金氧化的影响的新兴趣。本文的重点是水蒸气的存在如何直接改变选择性氧化过程。本文首先简要回顾了选择性氧化的基本原理，然后描述了有关水蒸气在 600 至 700 °C 温度范围内对各种氧化铬形成合金（铁基和镍基）氧化的影响的最新实验结果。气氛包括空气、空气-H2O、Ar-H2O和Ar-H2O-O2。然后简要描述了氧化铝形成合金在含 H2O 气氛中的行为。由于氢气是在水中氧化合金过程中产生的，因此它可以释放回气相或注入金属中（在那里它可以扩散到另一侧）。描述了在仅一侧被 H2O 氧化期间测量薄样品两侧氢浓度的实验。最后，试图根据一些一般原则对各种实验观察结果进行分类。
Essentially all alloys and coatings that are resistant to corrosion at high temperature require the formation of a protective (slowly-growing and adherent) oxide layer by a process known asselective oxidation. The fundamental understanding of this process has been developed over the years for exposure in pure oxygen or air. However, the atmospheres in most applications contain significant amounts of water vapor which can greatly modify the behavior of protective oxides. The development of oxy-fuel combustion systems in which fossil fuels are burned in a mixture of recirculated flue gas and oxygen, rather than in air, has caused renewed interest in the effects of water vapor and steam on alloy oxidation. The focus of this paper is on the ways the presence of water vapor can directly alter the selective oxidation process. The paper begins with a brief review of the fundamentals of selective oxidation followed by a description of recent experimental results regarding the effect of water vapor on the oxidation of a variety of chromia-forming alloys (Fe- and Ni-base) in the temperature range 600 to 700 °C. The atmospheres include air, air-H2O, Ar-H2O and Ar-H2O-O2. Then the behavior of alumina-forming alloys in H2O-containing atmospheres is briefly described. As hydrogen is produced during oxidation of alloys in H2O, it can be released back into the gas phase or injected into the metal (where it can diffuse through to the other side). Experiments in which hydrogen concentrations have been measured on both sides of thin specimens during oxidation by H2O on only one side are described. Finally, it is attempted to catalogue the various experimental observations under a few general principles.
