Abstract:
In this study we present the development of LaAlO3 coatings for TBC applications, by means of SPTS. LaAlO3 precursor solutions have been synthesized followed the in situ polymerization with citric acid [16-17]. The details of the solution synthesis, and deposition method, along with characterization of the deposits by means of Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) analysis, and microhardness measurements is reported. The effect of critical plasma spray deposition parameters on the resulting microstructural characteristics and phase composition of the developed coatings is discussed.
