The new enamels with high H3BO3-(NH4)(2) HPO4-AlPO4 content were studied, and the melting temperature of the enamels was adjusted by adding carbonate of alkali metal and alkaline earth metal. The enamels could spread slightly in the molten Al alloy observed by SEM and experiment. The components of the enamels were not detected with electron probe (EDAX-S-520) on the interface of Al alloy, but elemental Si of aluminum alloy was found in the silica-free enamels. Moreover, the components of the boron-free enamels were detected on the interface of Al alloy. The results show that the enamels with high B2O3-P2O5-AlPO4 content are resistant to the corrosion of molten Al.
