      abstract     = {Advanced thermal barrier coatings are essential to further
                      increase the efficiency of gas turbine engines. One limiting
                      factor of the TBC lifetime is the temperature dependent
                      formation of the thermally grown oxide (TGO) during thermal
                      exposure resulting in critical stress levels at the top
                      coat-bond coat interface. Oxide dispersion strengthened
                      (ODS) bond coats demonstrated slower oxygen scale growth
                      during thermal exposure in comparison to standard bond
                      coats.In this study for the first time TBC samples on
                      single-crystal substrates (comparable to CMSX4) with thin
                      ODS Co-based flash coats on the same Co-based bond coat
                      (Amdry 995) and a porous atmospherically plasma sprayed
                      (APS) yttria stabilized zirconia (YSZ) topcoat were
                      manufactured by thermal spray techniques and evaluated with
                      respect to their thermal cyclic behavior. As the major
                      performance test cyclic burner rigs, which can establish
                      thermal conditions similar to those in gas turbines, were
                      applied.TBC samples with the new material combination show
                      superior performance compared to previous samples. Cross
                      sections of the samples were analyzed by scanning electron
                      and laser scanning microscopy. Lifetime data and failure
                      mode of the samples are discussed with respect to material
                      properties such as thermal expansion coefficients,
                      microstructural changes and TGO growth.},
