Change in phase compositions for two different feedstocks of yttria stabilized zirconia coatings upon annealing. P is the starting feedstock powder; A–S is the as-sprayed coating. The annealing times at three different temperatures are indicated on the graphs. Note the convergence of mass fractions in graphs (a) and (b) of the coatings annealed for 100 h at 1400 °C.
