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. Particle Coating in a Wurster Type Bed

   Author : Stina Karlsson; Chalmers tekniska högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drying; Particle; Tracking technique; Spouted bed; Fluidisation; Multiphase flow; CFD; Trajectory; Coating; Wurster;

   Abstract : The Wurster bed process is frequently used for film coating. In the Wurster bed, particles circulate in the equipment and are sprayed with a liquid which forms a coating when dry. The procedure is repeated until the desired characteristics of the coating layer are obtained. READ MORE

5. 3. High temperature galling : influencing parameters and mechanisms

   Author : Leonardo Pelcastre; Jens Bergström; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements; Centrumbildning - Centrum för högpresterande stål CHS ; Centre - Centre for High Performance Steel CHS ;

   Abstract : Damage of forming tools at elevated temperatures is a major problem in metal forming processes such as hot stamping. Of special importance is the occurrence of adhesion and gross material transfer from the work-piece to the tool surface, a phenomenon known as galling. READ MORE

6. 4. Studies of electrically conductive textile coatings with PEDOT:PSS

   Author : Maria Åkerfeldt; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; textile coating; conductive coating; conjugated polymers; coating parameters; PEDOT:PSS; Textile technology; Textiles and Fashion General ; Textil och mode generell ;

   Abstract : This study investigates electrically conductive coatings of textiles, obtained with a direct coating and the addition of poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS) dispersion to a thickened polyurethane (PU)-based formulation. Textiles with enhanced electrical conductivity have potential applications in antistatic, electrostatic discharge protective, electromagnetic interference shielding, sensoric and temperature-regulating products.
