      abstract     = {Yttria stabilized zirconia (YSZ) is often applied as
                      thermal barrier coating on metal parts as e.g. turbine
                      blades made of nickel base super alloys. The coating process
                      in combination with the preconditioning of the substrate
                      material induces characteristic residual stress
                      distributions in the coating system consisting of topcoat,
                      bondcoat and the substrate material. Knowledge about the
                      residual stress depth distribution in the coating and at the
                      interfaces down to the substrate material is essential for
                      the assessment of the mechanical integrity and the
                      reliability of the coating. In this regard the stability of
                      the microstructure and the residual stresses is of
                      particular interest; hence this forms the scope of our
                      investigations. Yttria (8 $wt.\%)$ stabilized zirconia with
                      a NiCoCrAlY bondcoat was deposited by atmospheric plasma
                      spraying (APS) at different spray conditions on a nickel
                      base super alloy substrate material. The coatings were
                      subjected to different heat-treatment processes, i.e. static
                      aging and cyclic thermal loadings. Through surface scanning
                      using neutron diffraction was carried out for the as sprayed
                      condition and for the thermally loaded samples. Based on the
                      measured diffraction data the stability of the
                      microstructure (phases) and the residual strain/stresses
                      through the depths of the coating system were assessed.},
