      abstract     = {Columnar structured thermal barrier coatings (TBCs) have
                      been intensively investigated due to their potential to
                      enhance the durability and reliability of gas turbine engine
                      components. These coatings consist of vertically aligned
                      columns that provide excellent resistance to thermal
                      cycling. In this study, the lifetime of columnar
                      suspension-plasma-sprayed (SPS) TBCs was evaluated using
                      burner rig tests. The tests were carried out under
                      high-temperature conditions. Significantly, the
                      pre-oxidation of the bondcoat during diffusion bonding
                      treatment was found to have a substantial impact on the
                      performance of the SPS TBCs. The optimized treatment
                      resulted in columnar SPS TBCs demonstrating excellent
                      thermal stability and resistance under the test conditions.
                      The lifetime of the coatings was significantly extended
                      compared to conventional TBCs by pre-oxidation of the
                      CoNiCrAlY bondcoat in argon, which suggests that columnar
                      SPS TBCs have great potential for use in gas turbine
                      engines.},
