Electrochemical and metallographic evaluation of alloys C-22 and 625
- Framatome Cogema Fuels, Las Vegas, NV (United States)
Electrochemical cyclic potentiodynamic polarization (CPP) experiments were performed on Alloys C-22 and 625 to evaluate their susceptibility to localized corrosion in acidic brines of various salt content at 90{degrees}C. The microstructures of both tested and untested specimen`s were evaluated by optical microscopy. This paper presents the results showing the effect of chloride ion concentration on the pitting and crevice corrosion behavior of these alloys, and the relationship of the observed microstructures to the resulting surface degradation modes.
