Phase transformations in air plasma-sprayed yttria-stabilized zirconia thermal barrier coatings

Phase transformations in air plasma-sprayed thermal barrier coatings composed of ZrO2 – 8 wt.% Y2O3 (zirconia - 8 wt.% yttria) are studied using X-Ray diffraction and Rietveld refinement measurements. Samples of TBC deposited onto Inconel 625 substrate were fabricated and heat treated at two differe...
