Study on the Corrosion of Electrode Materials in Iron Phosphate Glass Melts
Inconel alloy 690 and Inconel alloy 693 were chosen as the electrode materials in this study and their corrosion behaviors in iron phosphate glass melt containing low activity (LAW) nuclear waste was explored. The corrosion losses in size and weight of different materials in glass melt were calculated. The corrosion layer formed on the surface of the alloys was analyzed by Scanning Electron Microscope (SEM), Energy Dispersive X-Ray analysis (EDS) and X-ray diffraction (XRD), and the corrosion mechanism was discussed. Results show that the Inconel alloy 693 is more stable than the Inconel alloy 690 in the glass melt. A kind of solid solution, (Fe, Cr)2O3, was believed to be the main crystalline phase in the corrosion layer on the surface of alloy samples.
