摘要	The paper mainly investigated the protective property, structure and composition of the oxide film on Alloy 625 in a lithium borate buffer solution (pH(300 degrees C) = 6.93) in the temperature range of 25-300 degrees C. The methods used were electrochemical measurements and XPS analysis. As temperature increased, the protective property of the oxide film degraded, and the structure varied from a singe-layer to double-layer. The oxide film consisted of Cr(2)O(3) and Cr(OH)(3) at 25 and 150 degrees C, while it contained Ni(OH)(2), in addition to Cr(2)O(3) and Cr(OH)(3) at 250 and 300 degrees C. This was mainly attributed to the temperature-induced variation of composition and protective property of the barrier layer. (C) 2009 Elsevier Ltd. All rights reserved.
