| 英文摘要 | The yttria-stabilized zirconia (YSZ) coatings have been widely used as thermal barrier coatings (TBCs). In order to investigate the factors that influenced the thermal conductivity of TBCs, bulk YSZ ceramics with different grain sizes were prepared via hot-pressing sintering methods under different annealing conditions. The quantitative effects of the phase and the grain size on the thermal conductivity were analyzed. Based on electron backscatter diffraction images (EBSD) of YSZ ceramics, the distribution of grain boundaries and tetragonal phase were obtained. And thermal conductivities of grain boundaries and tetragonal phase were calculated by finite element models and Fourier's equation. The thermal conductivities of grain boundaries and tetragonal phase are 2.65 W/(m·K) and 1.54 W/(m·K), respectively. The results reveal that the thermal conductivity of tetragonal phase is higher than that of the YSZ ceramic (2.31 W/(m·K)), while grain boundary's is lower than that of the YSZ ceramic. © 2017, Science Press.
