The effects of metallurgical structures of different alloyed glass mold cast irons on the mold performance

Cast irons are commonly used as mold material in production of glass materials. Since wear and oxidation are the main failure mechanisms that limit the surface life of glass molds, the aim of the present study was to examine the wear and oxidation behavior of cast irons by the addition of alloying elements. Glass mold cast irons must exhibit both wear resistance and oxidation resistance and this dual requirement can be met by D-type graphite structure and small amounts of Mo, Ni and Cu alloying.
