      abstract     = {During the past decade, gadolinium zirconate (Gd2Zr2O7,
                      GZO) has attracted interest as an alternative material to
                      partially yttria-stabilized zirconia (YSZ) for thermal
                      barrier coatings (TBCs). Despite the well-known benefits of
                      GZO, such as lower thermal conductivity and superior
                      temperature capability compared to YSZ, processing of GZO
                      via atmospheric plasma spraying (APS) still remains a
                      challenge. Here, we report on APS experiments which were
                      performed to investigate the influence of processing on GZO
                      microstructure and lifetime of GZO/YSZ double-layer TBCs.
                      Different microstructures of GZO were produced and
                      characterized in terms of porosity, stoichiometry, Young′s
                      modulus, and their effects on the lifetime of YSZ/GZO
                      double-layer TBCs were discussed. Particle diagnostics were
                      utilized for the optimization of the process parameters with
                      respect to different microstructures of GZO and
                      stoichiometry. It was found that both cumulative porosity of
                      GZO and pore size distribution, which alter the Young′s
                      modulus significantly, govern the lifetime of double layers.
                      In addition, it was shown that the deviation in GZO
                      stoichiometry due to gadolinia evaporation in the
                      investigated range does not display any critical effect on
                      lifetime.},
