  1. 1. Design of Thermal Barrier Coatings A modelling approach

    University dissertation from Trollhättan : University West

    Author : Nicholas Curry; Mohit Kumar Gupta; Högskolan Väst.; Högskolan Väst.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing and materials engineering; Produktions- och materialteknik; Industrial Gas Turbine; Aero Turbine; Thermal Barrier Coating; Atmospheric Plasma Spraying; Suspension Plasma Spraying; Thermal Conductivity; Thermo-cyclic fatigue; Thermal Shock; Thermal barrier coatings; Microstructure; Thermal conductivity; Young’s modulus; Interface roughness; Thermally grown oxide; Lifetime; Finite element modelling; Design;

    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

  2. 2. Thermal Barrier Coatings for Diesel Engines

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Anders Thibblin; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.

  3. 3. Thermal Cycling, Creep- and Tensile Testing of Cast Exhaust Materials at Elevated Temperatures

    University dissertation from STOCKHOLM : KTH Royal Institute of Technology

    Author : Christian Öberg; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; creep; constant-load; thermal cycling; tensile test; cast materials; cast iron; exhaust materials.; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : An exhaust manifold of a truck engine is subjected to tough conditions. As the truck is started, operated and shut down, it becomes subjected to thermal cycling up to around 800°C. At such high temperatures, corrosion, fatigue and creep are active degradation mechanisms. READ MORE
