  1. 1. The Prediction of Fluid Flow, Particle In-Flight and Coating Characteristics in Atmospheric Plasma Spraying

    Författare :Per Nylén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle temperature; coating temperature; coating thickness; particle velocity; plasma spraying; fluid flow; modelling;

    Sammanfattning : The aim of this thesis is to make a contribution to the development and application of models for the simulation and optimisation of plasma spray processes in production engineering. In particular, focus is placed on the development, combination and application of models for coating deposition and robot motion optimisation, the prediction of coating temperatures during deposit, the simulation of the plasma flow field, and in-flight characteristics of injected particles.

  3. 2. Suspension plasma sprayed thermal barrier coatings for internal combustion engines

    Författare :Wellington Uczak de Goes; Nicolaie Markocsan; Mohit Kumar Gupta; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coatings; Suspension Plasma Spraying; Gadolinium Zirconate; Internal Combustion Engines; Engine Efficiency; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : The upward trend in internal combustion engine efficiency is likely driven by the depletion of fossil fuels. Since no replacement in sight can deliver energy comparable to the conventional oil, there is a need to use it more rationally and effectively. LÄS MER

  4. 3. Design of Thermal Barrier Coatings

    Författare :Nicholas Curry; Nicolaie Markocsan; Per Nylén; Matthias Oechsner; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Gas Turbine; Aero Turbine; Thermal Barrier Coating; Atmospheric Plasma Spraying; Suspension Plasma Spraying; Thermal Conductivity; Thermo-cyclic fatigue; Thermal Shock; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Thermal barrier coatings (TBC’s) are used to provide both thermal insulation and oxidation protection to high temperature components within gas turbines. The development of turbines for power generation and aviation has led to designs where the operation conditions exceed the upper limits of most conventional engineering materials. LÄS MER

  5. 4. 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
