      abstract     = {Thermal barrier coatings (TBC) are used to protect hot path
                      components of gas turbines from hot combustion gases. For a
                      number of decades, in the case of aero engines TBCs are
                      usually deposited by electron beam physical vapour
                      deposition (EB-PVD). EB-PVD coatings have a columnar
                      microstructure that guarantees high strain compliance and
                      better solid particle erosion than PS TBCs. The main
                      drawback of EB-PVD coating is the deposition cost that is
                      higher than that of air plasma sprayed (APS) TBC. The major
                      scientific and technical objective of the UE project
                      TOPPCOAT was the development of improved TBC systems using
                      advanced bonding concepts in combination with additional
                      protective functional coatings. The first specific objective
                      was to use these developments to provide a significant
                      improvement to state-of-the-art APS coatings and hence
                      provide a cost-effective alternative to EB-PVD. In this
                      perspective one standard porous APS, two segmented APS, one
                      EB-PVD and one PS-PVD (TM) were tested at 700 degrees C in a
                      solid particle erosion jet tester, with EB-PVD and standard
                      porous APS being the two reference systems.Tests were
                      performed at impingement angles of 30 degrees and 90
                      degrees, representative for particle impingement on trailing
                      and leading edges of gas turbine blades and vanes,
                      respectively. Microquartz was chosen as the erodent being
                      one of the main constituents of sand and fly volcanic ashes.
                      After the end of the tests, the TBC microstructure was
                      investigated using electron microscopy to characterise the
                      failure mechanisms taking place in the TBC.It was found that
                      PS-PVD (TM) and highly segmented TBCs showed erosion rates
                      comparable or better than EB-PVD samples. (C) 2011 Elsevier
