  1. 1. Thermal Barrier Coatings : Durability Assessment and Life Prediction

    Author : Robert Eriksson; Sten Johansson; Michael Schütze; Linköpings universitet; []
    Keywords : ;

    Abstract : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. READ MORE

    Abstract : Atmospheric plasma sprayed (APS) thermal barrier coatings (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. TBC is a duplex material system consisting of an insulating ceramic topcoat layer and an intermetallic bondcoat layer. READ MORE

  4. 4. Thermal Barrier Coatings for Diesel Engines

    Author : Anders Thibblin; Ulf Olofsson; Stefan Jonsson; Senad Dizdar; Uta Klement; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; thermal barrier coatings; diesel engine; thermal cycling fatigue; heat flux; running-in; exhaust manifolds; yttria-stabilized zirconia; gadolinium zirconate; lanthanum zirconate; Machine Design; Maskinkonstruktion;

    Abstract : Reducing the heat losses in heavy-duty diesel engines is of importance for improving engine efficiency and reducing CO2 emissions. Depositing thermal barrier coatings (TBCs) onto engine components has been demonstrated to have great potential to reduce heat loss from the combustion chamber as well as from exhaust components.

  5. 5. Design of Microstructures in Thermal Barrier Coatings : A Modelling Approach

    Author : Mohit Kumar Gupta; Per Nylén; Robert Vaβen; Högskolan Väst; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal barrier coatings; microstructure; thermal conductivity; Young‘s modulus; lifetime; finite element modelling; design; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Plasma sprayed Thermal Barrier Coating systems (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. The material that is most commonly used in these applications is Yttria Stabilized Zirconia (YSZ) because of this ceramic’s favourable properties, such as low thermal conductivity, phase stability to high temperature, and good erosion resistance.
