      abstract     = {Suspension plasma spraying (SPS) as a relatively new
                      spraying technology has great potential on depositing high
                      performance thermal barrier coatings (TBCs). In some cases,
                      however, columnar SPS TBCs show premature failure in thermal
                      cycling test. To explain the reasons of such failure, a
                      failure mechanism for columnar SPS TBCs was proposed in this
                      work. The premature failure of TBCs might be related to the
                      radial stresses in the vicinity of top coat/bond coat
                      interface. These radial stresses were introduced by the
                      thermal misfit and the roughness of bond coat. According to
                      this mechanism, two architecture designs of SPS TBCs were
                      applied to improve the thermal cycling lifetime. One was a
                      double layered top coat design with a lamellar atmospheric
                      plasma sprayed (APS) sub-layer and a columnar SPS top-layer.
                      The other one was a low roughness bond coat design with a
                      columnar SPS top coat deposited on a low roughness bond coat
                      which was grinded before the spraying. With both designs,
                      lifetimes of SPS TBCs were significantly extended.
                      Especially, a lifetime even better than conventional APS
                      TBCs was achieved with the double layered design},
