摘要	Microstructural characteristics of the oxide films formed on Alloy 690 TT after the exposure in oxygenated pure and primary water at 325 degrees C were investigated. Change in water chemistry from pure to primary water was found to vary the film structure from duplex to triple layer, and lead to change in the morphology of NiO on the surface. The increased pH and solution conductivity of primary water also accelerate the dissolution of Cr species and enhance the electrochemical corrosion. The Ni-rich and Cr-depleted inner layer formed under both water chemistries is porous and not protective. The related oxidation mechanism is discussed. (C) 2013 Elsevier Ltd. All rights reserved.
