      abstract     = {Thermal barrier coatings (TBCs)s are extensively used to
                      enable enhanced efficiency in gas turbines for both energy
                      and aviation sector. TBCs nowadays are becoming prime
                      reliant and alongside with the electron-beam physical vapor
                      deposition (EB-PVD) various thermal spray technologies are
                      intensively used for the deposition of these advanced
                      protective coating systems under increasingly harsh
                      conditions in terms of thermo-cyclic loadings and corrosive
                      environments. Current developments cover e.g. improved
                      coating microstructures, new materials and multi-functional
                      coating systems. Especially columnar architectures attract
                      major interest as they offer high strain tolerance similar
                      to EB-PVD type coatings which can be achieved e.g. by
                      suspension plasma spraying (SPS) or plasma spray physical
                      vapor deposition (PS-PVD). The relation between process
                      condition and microstructure will be outlined. In addition,
                      results of thermal cycling of such columnar structured
                      coatings will be shown and discussed. Improved capabilities
                      to withstand increasing temperatures and harsh corrosive
                      environments typically are achieved by multi-layer coating
                      designs which comprise new material top-coats or composite
                      inter-layers. Processing issues of TBCs with top-layers from
                      high-temperature capable materials as e.g. rare earth oxides
                      as pyrochlores, aluminates and complex perovskites will be
                      reviewed. Degradation modes of those advanced coating
                      systems under relevant test conditions are reviewed giving
                      some indication for further improvements.Finally, also some
                      remarks on the use of TBCs on ceramic matrix composites will
                      be given.},
