| 英文摘要 | Substitutional point defects alter the thermal conductivity of ABO(3) type compound by influencing the phonon scattering. Coatings of Sr(Zr0.9Yb0.05Gd0.05)O-2.95 are prepared with different processing parameters and then characterized using XRD, EDS, EBSD and SEM. XRD analysis confirmed that SrZrO3 is the major phase. Microsticks oriented in different directions are found from the SEM observations. The existence of Yb (1.79 wt %) and Gd (5.82 wt %) in the Sr(Zr0.9Yb0.05Gd0.05)O-2.95 coating is confirmed from the EDS analysis. Electron back scattered diffraction investigation demonstrated that majority of grains are in 0.3-0.6 mu m range. Among the coatings prepared with different processing parameters, the Sr(Zr0.9Yb0.05Gd0.05)O-2.95-2 coatings with the Ar (L/min) and H-2 (L/min) flow of 35 and 7 provided minimum thermal conductivity. The lower thermal conductivity of the coating is attributed to the concentration of point defects and the optimal processing parameters. |
