1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Shivang Parmar; [2023]
   Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

   Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE

3. 2. Failure analysis of suspension plasma sprayed thermal barrier coatings

   University essay from Högskolan Väst/Forskningsmiljön produktionsteknik(PTW)

   Author : Mohammed Jasim; [2017]
   Keywords : Failure analysis; Suspension plasma sprayed; Thermal barrier coating;

   Abstract : Thermal barrier coatings (TBC) are proven to protect the hot section of components operated under elevated temperature. Suspension Plasma Spray (SPS) is an emerging manufacturing process that is used to produce TBCsI, It has the ability to deposit a thinner TBC that has finer microstructure than coatings deposited using traditional Atmospheric Plasma Spray (APS).

4. 3. Isothermal Oxidation Study of Gd2Zr2O7/YSZ Multi-Layered Thermal Barrier Coatings

   University essay from Högskolan Väst/Avd för tillverkningsprocesser

   Author : Ran Li; [2015]
   Keywords : Multi-layered thermal barrier coating; isothermal oxidation; suspension plasma spray;

   Abstract : Conventional yttria stabilized zirconia (YSZ) are widely used in the gas turbine to protect the substrate material from high temperature. But the common YSZ top coatings have limitations at higher temperature (above 1200 ℃) due to significant phase transformation and intensified sintering effect. READ MORE

5. 4. Comparison of stress behaviour in thermal barrier coatings using FE analyses

   University essay from Institutionen för ingenjörsvetenskap

   Author : Tobias Hansson; Kristoffer Skogsberg; [2012]
   Keywords : TBC; TGO; FE Analysis; microstructure; surface rougness; residual stresses;

   Abstract : The objective of this thesis project was to compare the stress behaviour in thermal barrier coatings (TBCs) with FE analyses in both 2D and 3D. The main focus was to analyse the vertical stresses in the topcoat (TC) and how they varied in relation to different thicknesses of the thermally grown oxide (TGO), spraying methods of the bondcoat (BC) and the topography of the BC.
