  1. 1. Erosion Behaviour of Thermal Barrier Coatings

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

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

    Sammanfattning : 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. LÄS MER

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

    Magister-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

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

    Sammanfattning : 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. LÄS MER

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

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Materialvetenskap

    Författare :Siamak Kianzad; [2017]
    Nyckelord :Materials; TBC; Thermal barrier coating; heat flux; crack; combustion chamber; heavy duty diesel engine; single-cylinder; dummy valve; 8YSZ; YSZ; segmented cracks; radiative heat transfer; lanthanum gadolinium; EB-PVD; PVD; APS; CVD; horizontal cracks; vertical cracks; crack propagation; crack initiation;

    Sammanfattning : 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. LÄS MER

  5. 4. Termisk cykling provuppställning konstruktion och provning av TBCs för dieselmotorapplikation

    Magister-uppsats, Högskolan Väst/Forskningsmiljön produktionsteknik(PTW)

    Författare :Sourabh Bhoje; [2017]
    Nyckelord :Thermal Barrier Coatings; test methods;

    Sammanfattning : Thermal barrier coatings (TBCs) thermally insulate the substrate from high temperature exposure. This work attempted to simulate real engine thermal cyclic conditions by designing a test method to evaluate the thermal cyclic fatigue (TCF) performance of different coatings applied inside exhaust manifold of a diesel engine.

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

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

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

    Sammanfattning : 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. LÄS MER
