1. 11. Life Prediction and Mechanical Behavior of Thermal Barrier Coatings

   Författare :Yan Liu; Materialteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stress intensity factors; Macro-cracks; Micro-cracks; Mechanical behaviour; Thermal barrier coatings; Life prediction; Material technology; Materiallära; materialteknik;

   Sammanfattning : Delamination and spallation of thermal barrier coating (TBC) systems, used in hot parts of gas turbines, have been studied with respect to thermal fatigue. TBCs with and without pre-existing cracks were investigated. Thermal shock tests were performed until coating spallation. LÄS MER

3. 12. High-temperature degradation of plasma sprayed thermal barrier coating systems

   Författare :Robert Eriksson; Sten Johansson; Christer Burman; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Thermal barrier coating systems (TBCs) are used in gas turbines to prevent high-temperature degradation of metallic materials in the combustor and turbine. One of the main concerns regarding TBCs is poor reliability, and accurate life prediction models are necessary in order to fully utilise the beneficial effects of TBCs. LÄS MER

4. 13. Microstructure and Thermal Conductivity of Liquid Feedstock Plasma Sprayed Thermal Barrier Coatings

   Författare :Ashish Ganvir; Nicolaie Markocsan; Per Nylén; Ru Lin Peng; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microstructure; Thermal Barrier Coating; Axial Injection; Suspension Plasma Spraying; Suspension High Velocity Oxy Fuel Spraying; Solution Precursor Plasma Spraying; Porosity; Thermal Diffusivity; Thermal Conductivity; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Thermal barrier coating (TBC) systems are widely used on gas turbine components to provide thermal insulation and oxidation protection. TBCs, incombination with advanced cooling, can enable the gas turbine to operate at significantly higher temperatures even above the melting temperature of the metallic materials. LÄS MER

5. 14. Design of Suspension Plasma Sprayed Thermal Barrier Coatings

   Författare :Ashish Ganvir; Nicolaie Markocsan; Mohit Kumar Gupta; Per Nylén; Christian Moreau; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microstructure; Thermal Barrier Coatings; Axial Injection; Suspension Plasma Spraying; Porosity; Thermal Conductivity; Fracture Toughness; Lifetime; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Thermal barrier coatings (TBCs) are widely used on gas turbine components to provide thermal insulation, which in combination with advanced cooling, can enable the gas turbine to operate at significantly higher temperatures even above the melting temperature of the metallic components. There is a permanent need,mainly due to environmental reasons, to increase the combustion temperature inturbines, hence new TBC solutions are needed. LÄS MER

7. 15. Delamination in APS applied thermal barrier coatings : life modelling

   Författare :Magnus Jinnestrand; Esteban Busso; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Thermal barrier coatings, TBCs, are used in gas turbines as a thermal shield resulting in lower temperature in coated components. The decrease of temperature allows higher gas temperatures in the turbine, which increase the efficiency. LÄS MER
