The residual stresses play a significant position in the production of Plasma sprayed coatings. The substrate material was nickel-based alloy (SS304), and CoNiCrAlY was plasma-sprayed on the substrate as the bond coating. As the top coating, zirconia with 8 mol% yttria and Zirconia Ceria powder was plasma-sprayed on the substrate. The residual stress was measured by a X-ray diffraction method. In this investigation, the residual stress was measured by sin2 ψ x-ray diffraction method in plasma sprayed Yttria Stabilised Zirconia and Zirconia Ceria powder coatings
