Interaction of multicomponent disilicate(Yb0.2Y0.2Lu0.2Sc0.2Gd0.2)2Si2O7 with molten calcia-magnesia-aluminosilicate
文献摘要:
Environmental barrier coating(EBC)materials that are resistant against molten calcia-magnesia-aluminosilicate(CMAS)corrosion are urgently required.Herein,multicomponent rare-earth(RE)disilicate((Yb0.2Y0.2Lu0.2Sc0.2Gd0.2)2Si2O7,(5RE)2Si2O7)was investigated with regard to its CMAS interaction behavior at 1400℃.Compared with the individual RE disilicates,the(5RE)2Si2O7 material exhibited improved resistance against CMAS attack.The dominant process involved in the interaction of(5RE)2Si2O7 with CMAS was reaction-recrystallization.A dense and continuous reaction layer protected the substrate from rapid corrosion at high temperatures.The results demonstrated that multicomponent strategy of RE species in disilicate can provide a new perspective in the development of promising EBC materials with improved corrosion resistance.
