摘要	Oxide films formed on Alloy 690 exposed to 290 degrees C water containing 3 ppm O(2) were investigated. It was found that Cr rich oxides form initially through solid-state reactions. Ni-Fe spinels gradually develop on surface layer by precipitation with increasing immersion time. Initially formed Cr rich oxides react with outwards diffusing Ni and Fe to form small spinel particles which then vanish gradually. An inner layer develops from oxide/matrix interface through inward diffusion of oxidant. Cr is preferentially oxidized and tends to dissolve into solution. The resultant inner layer consists of predominant NiO which cannot serve as a protective barrier layer. (C) 2011 Elsevier Ltd. All rights reserved.
