摘要

The life time of the Zircaloy-4 alloy is linked to the role that intermetallic particles play during the growth of the zirconia scale. In the present work, a photoelectrochemical technique (PEC), has been used to study the phenomena of oxidation of intermetallic particles but also of dissolution of thermal oxidised particles. Both phenomena have been addressed in the literature and studied in particular with TEM; in this work, they were clearly imaged by photoelectrochemical microscopy at a mesoscopic view. Our results do contribute to a better understanding of the major impact that intermetallic precipitates could have on the oxidation rate.
