Data Compiling and Analysis of Oxide Film Growth on Nickel-Base Alloys in High Temperature Water

A logarithmic relationship for the oxide film thickness of Nickel-based alloys in high temperature water versus immersion time or dissolved hydrogen (DH) is identified based on the compilation and analysis of the experimental data reported in some literature. A theoretical equation is used to quantify the correlations between thickness and time or DH. The logarithmic correlation between inner layer thickness and iron content in alloy matrix and the linear correlation between outer layer thickness and iron content in alloy matrix are primary identified by fitting the experimental data in our own work. The correlation of oxidation kinetics and stress corrosion cracking growth rate is discussed.
