Abstract

Abstract

The internal stress in the oxide film of zirconium alloy is an important factor in the corrosion kinetics of zirconium alloy. At present, there is no unified method to obtain the internal stress in the oxide film, and the data is quite different. Based on the traditional experimental and theoretical methods, the double layer oxidation bending model of ZrO₂/Zr is established, the internal stress in the oxide film under different corrosion conditions is calculated, the change rule of the internal stress is obtained and the influencing factors is analyzed, which provides a more reliable way for the research of the internal stress in the oxide film of zirconium alloy.
