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

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

    Abstract : 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.

  4. 2. Design of Thermal Barrier Coating Systems

    Author : Nicholas Curry; Per Nylén; Nicolaie Markocsan; Robert Vassen; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coating; Atmopsheric Plasma Spraying; Thermal Conductivity; Thermo-cyclic fatigue; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : 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. READ MORE

  5. 3. A Study of the Adhesion Strength of Plasma Sprayed Coatings

    Author : Fouzi Bahbou; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Splat.; Surface roughness; Mechanical anchoring; Grit blasting; Adhesion strength; Protal® process; Fractal analysis; Thermal spraying; Coating; Surface pre-treatment;

    Abstract : Surface preparation prior to thermal spraying is a key factor in ensuring a good adhesion of the coating onto the part to be coated. Surface pre-treatment conditions and methods have mainly been developed experimentally and have changed little over the years. READ MORE

  6. 4. An Experimental Study of Submerged Entry Nozzles (SEN) Focusing on Decarburization and Clogging

    Author : Arashk Memarpour; Pär Jönsson; Torbjörn Carlberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory; SEN; Clogging; REM; Coating; glaze; alkaline; Post- Mortem; industrial preheating; ZrSi2; Graphite; Alumina; Oxidation; Al2O3-C; ZrO2-C; MgO-C; decarburization; reaction mechanism; Yttria Stabilized Zirconia; plasma spray-PVD coating;

    Abstract : The submerged entry nozzle (SEN) is used to transport the molten steel from a tundish to a mould. The main purpose of its usage is to prevent oxygen and nitrogen pick-up by molten steel from the gas. Furthermore, to achieve the desired flow conditions in the mould. READ MORE
