| 英文摘要 | The interfacial reaction between CaO-Y2O3 system and superalloy melt was systematically studied, and the relationship between reaction temperature and interfacial reaction was revealed. Innovative experimental methods combined with XRD and SEM-EDS characterization techniques were applied in this paper. The reaction behavior of CaO-Y2O3 c9eramic system and typical high activity superalloy interface reaction products, including phase and element distribution, has been systematically studied. The interface reaction is in the form of CaOY2O3+Al+S -> CaS+Y+CaAlYO4. CaAlYO4 composite oxide plays a key role in the reaction as a dielectric layer between the melt and the refractory. CaAlYO4 acts as the medium layer to ensure the desulfurization and yttrium addition of the superalloy melt. Temperature affects the chemical composition and reaction rate of the dielectric layer, which in turn determines the interface reaction process. Temperature dependent relationship of the interface reaction between melt and ceramic is explained in detail. The increase of reaction temperature changes the oxide composition of the medium layer and promotes the desulfurization and yttrium reaction. CaO-Y2O3 is a refractory system with both desulfurization and rare earth effect. |
