Figure 3
(a) The diffraction pattern of zirconia from the top coat. (b) The diffraction pattern of nickel obtained from the bond coat. (c) The way in which the Debye–Scherrer rings were fitted using GSAS-II. A reasonable fitting of the diffraction pattern can be observed. (d) The d spacing of the 101 reflection of zirconia as a function of the azimuthal angle around the Debye–Scherrer ring. The dots represent the d spacing obtained from the Debye–Scherrer ring and the solid line represents the fitting function for the dot data. Strain can be seen to result in a non-uniform Debye–Scherrer ring. |
