Abstract Alloy 22 (N06022) is a nickel-based alloy highly resistant to corrosion. In
aggressive conditions of high chloride concentration, temperature, and applied potential,
alloy 22 may suffer crevice corrosion, a form of localized corrosion. Several electrochemical
methods can be used to detect localized corrosion in metallic alloys. One of the most
popular for rapid screening is cyclic potentiodynamic polarization (CPP). This work

Abstract
Alloy 22 (N06022) is a nickel-based alloy highly resistant to corrosion. In aggressive conditions of high chloride concentration, temperature, and applied potential, alloy 22 may suffer crevice corrosion, a form of localized corrosion. Several electrochemical methods can be used to detect localized corrosion in metallic alloys. One of the most popular for rapid screening is cyclic potentiodynamic polarization (CPP). This work compares the repassivation potentials obtained using CPP to repassivation potentials obtained using the Tsujikawa-Hisamatsu Electrochemical method and the potentiostatic method.
