Abstract

The effects of dissolved hydrogen (DH) on the corrosion behavior of Alloy 182 in high temperature (320°C) water were studied using in situ electrochemical measurements and ex situ surface analyses. The film resistance and thickness increased with decreasing DH. Under conditions of DH=50cm³/kg and 30cm³/kg, the oxide film was very thin and predominantly consisted of Cr³⁺. At DH=5cm³/kg, the oxide film grew thicker, and the outer part consisted of NiO and spinel, with Cr³⁺ primarily located in the inner part. The underlying mechanism of stress corrosion cracking (SCC) susceptibility was considered.
