| Abstract Scope |
In comparison with graphite electrode, a metallic electrode for salt bath heat treatment, all-electric glass smelters, and primary aluminum production has potential advantages, such as energy saving, low greenhouse emission, excellent thermal shock resistance, and easy fabrication into complex shapes. However, erosion resistance is a concern. Nickel-based alloys have been used in a variety of severe operating conditions involving corrosive environment, elevated temperature, high stress and their combinations. To investigate the feasibility of nickel-based superalloy used as an electrode material for primary aluminum production, the erosion rate of an Inco nickel-based superalloy in a standard fluoride electrolyte melt was studied. The maximum erosion rate of the superalloy in the fluoride at 1000ºC is approximately 27 microns per hour in a three hours period. |
