      abstract     = {In modern gas turbines, highly loaded components are
                      internally cooled and furthermore covered with thermal
                      barrier coatings (TBCs) to withstand the harsh operating
                      conditions with temperatures exceeding the application limit
                      of such coatings. Under realistic operating conditions,
                      siliceous minerals, of a calcium-magnesium-aluminum-silicate
                      (CMAS) composition, are ingested into the turbine and
                      deposited on the TBCs. Besides erosion, this also leads to
                      degradation by chemical interaction.The plasma
                      spray-physical vapor deposition (PS-PVD) process is an
                      advanced method for manufacturing TBCs, which fills the gap
                      between traditional thermal spray processes and electron
                      beam physical vapor deposition (EB-PVD). Due to the unique
                      plasma conditions, coatings with columnar microstructures
                      exhibiting high strain tolerance can be created. However,
                      because of the high amount of open porosity the resistance
                      of such structures to CMAS and erosion attack was expected
                      to be low.In the present work, PS-PVD TBCs were investigated
                      in a burner rig facility under thermal gradient cycling
                      conditions and simultaneous CMAS attack. The interactions of
                      the PS-PVD-deposited YSZ and the CMAS melt were studied by
                      means of scanning electron microscopy (SEM) and energy
                      dispersive X-ray analysis (EDS) and compared to EB-PVD
                      coatings. Additionally, the resistance of PS-PVD TBCs to
                      erosion is compared to APS TBCs by means of room temperature
                      tests according to ASTM G76-13.},
