1. 1. Erosion Behaviour of Thermal Barrier Coatings

   University essay from Linköpings universitet/Konstruktionsmaterial

   Author : Caroline Wännman; [2021]
   Keywords : erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

   Abstract : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. READ MORE

3. 2. Understanding the effect of material composition and microstructure on the hot corrosion behaviour of plasma sprayed thermal barrier coatings

   University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

   Author : Ehsan Najafi; [2019]
   Keywords : Thermal barrier coatings; molten salt infiltration; TBC variations; hot corrosion test;

   Abstract : Thermal barrier coatings (TBC) are used in the hot sections of gas turbine engine in order to insulate the substrate at high temperature. Molten salt infiltration retards the durability of TBCs. The current standard material, i.e. READ MORE

4. 3. Measurement of Thermal Insulation properties of TBC inside the Combustion chamber

   Abstract : This master thesis project was performed in collaboration with Scania CV AB, Engine Materials group. The purpose with the project was to investigate different ceramic TBC (Thermal Barrier Coating) thermal insulation properties inside the combustion chamber. READ MORE

5. 4. Fabrication and evaluation of nickel containing nanofibres for solid oxide fuel cell anodes using electrospinning technique

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Ida Fransson; Tara Larsson; [2016]
   Keywords : Solid oxide fuel cell; 8YSZ; Ni; electrospinning; renewable energy; Technology and Engineering;

   Abstract : The energy demand of the world continues to increase, while world's resources are exploited over its capacity. One way of facing these demands is to extend the use of fuel cells. A fuel cell converts chemical energy into electrical energy through a series of chemical and electrochemical reactions. READ MORE
