| 英文摘要 | In recent years, numerous techniques have been developed to mimic nacre-like hierarchical architectures in order to improve the damage tolerance of materials. We present herein a simple strategy to fabricate such a hierarchical architectured Al2O3-Y2O3 composite coating via atmospheric plasma spraying. The evolution of the phase and microstructure of the Al2O3-Y2O3 composite coating were characterized under conditions of high-temperature exposure in air at 800-1350 A degrees C. The hardness and porosity of several typical coatings were determined. In situ formation of dense hierarchical architectured Al2O3-YAG composite coating with improved hardness was achieved after heat treatment at 1350 A degrees C. Compared with Al2O3 coating, elevated toughness was found for the hierarchical architectured Al2O3-YAG composite coating, which can be ascribed to the distribution of YAG phase that contributed to crack termination and deflection, and microbridging. After thermal aging treatment at 1350 A degrees C, the hierarchical architectured Al2O3-YAG composite coating was quite stable after 100 h of thermal exposure. Furthermore, the Al2O3-Y2O3 composite coating exhibited superior sintering resistance compared with the Al2O3 coating. |
