  1. 1. Adhesion strength of HVOF sprayed Inconel 718 coatings

    Author : Christophe Lyphout; Chalmers University of Technology; []
    Keywords : Adhesion Strength; Residual Stress; Inconel 718; Thermal spray; Finite Element Method; HVOF; High Velocity Oxy-Fuel;

    Abstract : Thermal spray technology in general is nowadays recognized as an industrial process, mature enough to apply coatings on different substrate materials that protect parts against wear, corrosion, heat, or combinations of these. The quality demands on coating homogeneity and adhesion strength are, nowhere more than in the automotive and aeronautic industries, continuously increasing. READ MORE

  2. 2. A Study of the Adhesion Strength of Plasma Sprayed Coatings

    Author : Fouzi Bahbou; Chalmers University of Technology; []
    Keywords : 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

  3. 3. Flocculation with Polyelectrolytes in Latex and Microbial Systems

    Author : Leif Eriksson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; floc strength; shear sensitivity; fractal dimension; floc structure; patch flocculation; adhesion; bridging; flocculation; charge compensation; adsorption; ionic strength; molecular weight; charge density; Cationic polyelectrolytes; latex; bacteria; activ; Physical chemistry; Fysikalisk kemi;

    Abstract : Adsorption of cationic polyelectrolytes onto polystyrene latices was studied as function of polymer chemical composition and molecular weight, polymer and surface charge density and ionic strength. The ratio between polymer charges and surface charges was close to one when distances between polymer and surface charges were equal. READ MORE

  5. 5. Wear mechanisms in sheet metal forming : Effects of tool microstructure, adhesion and temperature

    Author : Anders Gåård; Pavel Krakhmalev; Jens Bergström; Ulf Olofsson; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Galling; sheet metal forming; wear; friction; adhesion; temperature; Materialteknik; Materials Engineering;

    Abstract : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of lubricants, in combination with the introduction of high and ultrahigh-strength sheet materials, continuously increases the demands on the forming tools. READ MORE
