- Abstract
There are exceptionally extreme prerequisites anticipated from materials that are to be utilized as a part of aero plane engines. These materials ought to survive extreme working conditions with high operating temperature and pressure. Turbine section is the one where the impact of advancements in materials and material procedures can be best prized. The basic mechanical properties anticipated from all materials must be temperature dependent. Fabricating super alloys to meet the higher working temperature and requirements such as higher creep strength and better resistance to corrosion or oxidation is highly cumbersome. Cubic stabilized zirconia is a promising material in Thermal Barrier Coatings (TBCs) for high temperature applications, which can be utilized to climb the surface temperatures upto 1200°C. Our present work is focused on preparation of 8 mol% yttria-stabilized zirconia with 10 mol% ceria (10Ce-8YSZ) incorporated with Thoria. A wet chemical route powder synthesis method was applied to make homogeneous Yttria and Ceria-Stabilized Zirconia (YCSZ) ceramics from its core and Thoria was synthesized from its Nitrate independently and blended with YCSZ to upgrade its properties for high temperature coating application. The crystalline structure and morphological properties of the YCSZ nano particles were studied by using Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray emission Spectrometry (EDXS), X-ray Diffraction (XRD) and UV diffuse reflectance spectrum.
