| dc.description.abstract | The prevention of high-temperature corrosion on containment materials plays a critical role, and a corrosion mitigation plan is needed to achieve the target plant lifetime of 30 years. This paper analyzed two mitigation corrosion strategies (anodic and cathodic protection) in a eutectic ternary chloride molten salt, composed by 20.4wt.% KCl + 55.1wt.% MgCl2 + 24.5wt.% NaCl. The corrosion mechanism and corrosion rates were obtained through electrochemical impedance spectroscopy (EIS). Ni base alloys generate a protective scale layer (anodic protection) during 8 hours of immersion with a corrosion rate of 6.34 mm/year (In702) and 3.12 mm/year (HR224). Monitoring corrosion results were confirmed by scanning electron microscopy (SEM) and X-ray diffraction (XRD), obtaining alumina and chromia protective layers. | ca_ES |
