Effect of dissolved hydrogen on corrosion of Inconel Alloy 600 in high temperature hydrogenated water
TLDR
In this article, the effect of dissolved hydrogen (DH) levels on the Ni/NiO phase transition was investigated by employing electrochemical and exposure experiments, and the results showed that increasing DH in water decreased the thickness and the ionic defect transport resistance of the oxide film, in conjunction with the increase of Cr- but decrease of Ni-concentrations in the oxide.About:

Influence of dissolved oxygen concentration on the oxide film formed on Alloy 690 in high temperature water
TL;DR: In this paper, the properties of Alloy 690 oxide films under different dissolved oxygen (DO) concentrations in 290°C water were examined, and the results showed that the oxide films formed under low DO became much thicker when immersed under high DO, with gradual development of spinel particles and NiO base layer.

Effects of boundary migration and pinning particles on intergranular oxidation revealed by 2D and 3D analytical electron microscopy
Brian Langelier,S.Y. Persaud,S.Y. Persaud,Andreas Korinek,Travis Casagrande,Roger C. Newman,Gianluigi A. Botton +6 more
TL;DR: In this paper, Alloy 600 samples in the thermally treated (TT) and solution-annealed (SA) conditions were analyzed after exposure to 480°C hydrogenated steam, and 3D serial sectioning of the boundaries revealed strong variations in the intergranular oxide for 600TT, particularly in the depth of oxide penetration.

The mechanism of high temperature aqueous corrosion of stainless steels
TL;DR: In this article, it was shown that the corrosion rate of stainless steels in high temperature, deoxygenated water is controlled by the solid state diffusion of Fe ions along grain boundaries in the oxide layer.
