| 英文摘要 | In order to maximize the thermal cycling performance of Gd 2 Zr 2 O 7 coating, a double-layer structured Gd 2 Zr 2 O 7 / YSZ thermal barrier coating is designed. However, thermal mismatch and inferior mechanical properties of top coating often lead to the thermal cycling life reduction of Gd 2 Zr 2 O 7 /YSZ thermal barrier coating. In the present work, a scalable hybridizing strategy approach is put forward to tailor the thermal and mechanical properties of Gd 2 Zr 2 O 7 . A serials of GAlO 3-Gd 2 Zr 2 O 7 composites are therefore fabricated, resulting in a significant increase in the fracture toughness and hardness of Gd 2 Zr 2 O 7 with the rise in GdAlO 3 volume fraction. The coefficient of thermal expansion of Gd 2 Zr 2 O 7 decreases, while the thermal conductivity increases as the GdAlO 3 volume fraction increases. These composites exhibit low phonon thermal conductivity and radiative thermal conductivity due to the heterogeneous GdAlO 3 /Gd 2 Zr 2 O 7 grain boundaries, which not only decrease phonon conductivity but also impede radiative heat transfer. The thermal cycling performance of the GdAlO 3 /Gd 2 Zr 2 O 7 (33 vol%) composite coating is investigated, showing a high thermal cycling life. We believe the modified GdAlO 3 / Gd 2 Zr 2 O 7 composites are promising for advanced thermal barrier coatings. |
