  1. 1. Thermal barrier coatings for diesel engines

    Författare :Wellington Uczak de Goes; Nicolaie Markocsan; Mohit Kumar Gupta; Rogerio S. Lima; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coatings; Suspension Plasma Spraying; Gadolinium Zirconate; Internal Combustion Engines; Engine Efficiency; Termiska barriärbeläggningar; Plasmasprutning; Suspensionssprutning; Gadolinium; Zirkoniumdioxid; Förbränningsmotorer; Motoreffektivitet; Production Technology; Produktionsteknik;

    Sammanfattning : The upward trend in internal combustion engine efficiency is driven by the demands for emission reduction and fossil fuel depletion. No present alternative fuel can produce energy comparable to that produced by conventional oil; this necessitates the reasonable, efficient usage of oil. LÄS MER

  3. 2. A Methodology to Control the Microstructure of Plasma Sprayed Coatings

    Författare :Martin Friis; Materialteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Process map; Plasma spraying; process window; Thermal Barrier Coating; Zirconia; DPV2000; particle temperature; Material technology; particle velocity;

    Sammanfattning : The aim of this thesis is to enhance the overall understanding of the plasma spray process and increase control and reproducibility of the coating properties. This was performed by establishment of relationships between controllable process parameters, in-flight properties of the injected particles (velocity and temperature), and microstructure properties.
