Abstract
Abstract The microstructural characteristics of oxide films on 90Nb–10Zr (wt%) alloy in lithiated water were investigated to understand the oxidation process of β-Nb precipitates in Zr–1Nb (wt%) alloy. The outer layer of the alloy is faceted, and has loosely packed LiNbO 3 particles. Pores and nano-sized LiNbO 3 are present between the outer and the compact Nb 2 O 5 inner layer. Nb 2 O 5 reacted with LiOH to form LiNbO 3 and it dissolved into the corrosive environment to leave pores in the oxide films. The Zr oxidised and dissolved in Nb 2 O 5 . A degradation mechanism is proposed on the corrosion resistance of the Zr–1Nb alloy in lithiated water.
