Title: Corrosion behaviour of Fe-40Al-Zr at.% alloy in molten soda-lime glass
Author: A. HOTAR, V. HOTAŘ, F. NOVOTNÝ

Abstract: The corrosion behaviour of Fe-40Al-Zr at.% has been investigated in molten soda-lime glass at 1200 °C. The measurement of weight loss and surface change were used for explanation of the corrosion resistance. The alloying by 0.09 at.% Zr reduces the corrosion resistance of Fe-40Al-Zr against molten soda-lime glass in comparison with earlier tested Fe-25Al-5Cr alloy.
The corrosion mechanism of Fe-40Al-Zr alloy in molten soda-lime glass was also described. During reactions between tested iron aluminide and glass oxides, Al2O3 was generated and preferential oxidation of Zr-rich precipitates occurred.


Keywords: iron aluminide (FeAl type), corrosion behaviour, molten soda-lime glass
