Abstract

Electrochemical Impedance Spectroscopy (EIS) measurements were carried out in high tempera-ture water with Ni-based Alloy-182. The aim was to correlate the EIS results with differences in Stress Corrosion Cracking (SCC) susceptibility that is present around the Ni-NiO transition. There was a clear difference between the EIS results at and away from the Ni-NiO transition. To make a more quantitative correlation a simple equivalent circuit was used to fit the experimental data. A clear correlation between the CPE exponent (n) and the SCC susceptibility could be obtained. Ad-ditionally, it was shown that the high frequency arc of the EIS data was related to the diffuse double layer
