A Comparison of the Oxidation of Fe&bCr, Ni ? Cr and Co ? Cr alloys in oxygen and water vapour

TLDR
In this paper, the main features of the mechanisms of oxidation for specific groups of alloys are considered in the light of existing knowledge on the alloy and oxide properties determining these mechanisms.
Abstract
The rates and modes of oxidation of a wide range of pure Fe-Cr, Ni-Cr and Co-Cr alloys in 1 atm oxygen, and in 0.1 atm water vapour/0.9 atm argon contaminated with traces of air, at 1000°C are compared, using data originating largely from a single laboratory. The main features of the mechanisms of oxidation for specific groups of alloys are considered in the light of existing knowledge on the alloy and oxide Properties determining these mechanisms. Vergleich der Oxydation von Fe-Cr, Ni-Cr und Co-Cr in Sauerstoff und Wasserdampf Die Geschwindigkeit und der Verlauf der Oxydation zahlreicher Legierungen aus Fe-Cr, Ni-Cr und Co-Cr in Sauerstoff (1 at) und Wasserdampf (0,1 at) + Argon (0,9 at) + Spuren von Lu# als Verunreinigung bei 1000°C werden unter Verwendung von weitgehend aus einem einzigen Laboratorium stammenden Daten verglichen. Die kennzeichnenden Eigenschaften der Oxydationsmechanismen fur spezifische Legierungsgruppen werden im Lichte der verfugbaren Kenntnisse uber die Legierungs- und Oxid- eigenschaften betrachtet, welche die Oxydationsmechanismen bestimmen.

The oxidation behaviour of metals and alloys at high temperatures in atmospheres containing water vapour: A review

TL;DR: In this paper, the effect of water vapour on the formation of a more porous scale is discussed. But, while there is experimental evidence for altered mechanical behaviour, there is very little data on relevant mechanical properties.

Oxidation Behavior of Ferritic Stainless Steels under SOFC Interconnect Exposure Conditions

TL;DR: In this paper, the authors focused on the oxidation behavior of ferritic stainless steels during the isothermal oxidation in the dual environments and found that scales grown on the air side under these dual exposure conditions can be significantly different from scales growing on samples exposed to air on both sides.

Mechanism of breakaway oxidation of Fe–Cr and Fe–Cr–Ni alloys in dry and wet carbon dioxide

TL;DR: In this paper, the influence of carbide precipitation on alloy chromium diffusion and the ability of the alloy to form and maintain Cr-rich oxide layers was investigated, and the conditions leading to departure from the protective stage were discussed in terms of Cr 2 O 3 thermodynamic and kinetic stability.
