      abstract     = {The suspension plasma spraying (SPS) process has been
                      developed to permit the feeding of sub-micrometer-sized
                      powder into the plasma plume. In contrast to electron
                      beam-physical vapor deposition and plasma spray-physical
                      vapor deposition, SPS enables the cost-efficient deposition
                      of columnar-structured coatings. Due to their strain
                      tolerance, these coatings play an important role in the
                      field of thermal barrier coatings (TBCs). In addition to the
                      cost-efficient process, attention was turned to the TBC
                      material. Nowadays, yttria partially stabilized zirconia
                      (YSZ) is used as standard TBC material. However, its
                      long-term application at temperatures higher than 1200 °C
                      is problematic. At these high temperatures, phase
                      transitions and sintering effects lead to the degradation of
                      the TBC system. To overcome those deficits of YSZ,
                      Mg-Al-spinel was chosen as TBC material. Even though it has
                      a lower melting point (~2135 °C) and a higher thermal
                      conductivity (~2.5 W/m/K) than YSZ, Mg-Al-spinel provides
                      phase stability at high temperatures in contrast to YSZ. The
                      Mg-Al-spinel deposition by SPS resulted in
                      columnar-structured coatings, which have been tested for
                      their thermal cycling lifetime. Furthermore, the influence
                      of substrate cooling during the spraying process on thermal
                      cycling behavior, phase composition, and stoichiometry of
                      the Mg-Al-spinel has been investigated.},
