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

    Author : Christophe Lyphout; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

    University dissertation from Göteborg : Chalmers University of Technology

    Author : M. Fouzi Bahbou; Fouzi Bahbou; Högskolan Väst.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Industrial engineering and economy Manufacturing engineering and work sciences Manufacturing engineering; TEKNIKVETENSKAP Industriell teknik och ekonomi Produktion och arbetsvetenskap Produktionsteknik; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik; Grit blasting; Thermal spraying; Coating; Surface pre-treatment; Surface roughness; Fractal analysis; Adhesion strength; Mechanical anchoring; Protal® process; Splat; Splat.;

    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

    University dissertation from Institute for Surface Chemistry, Box 5607, S-114 86 Stockholm, Sweden

    Author : Leif Eriksson; Lund University.; Lunds universitet.; [1997]
    Keywords : 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

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

    University dissertation from Karlstad : Karlstad University

    Author : Anders Gåård; Karlstads universitet.; Karlstads universitet.; Karlstads universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Materials Engineering; Galling; sheet metal forming; wear; friction; adhesion; temperature;

    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

  5. 5. Strength and Stability of Interfaces in Cemented Carbides

    University dissertation from Karlstad : Karlstad University

    Author : Mikael Christensen; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adhesion; segregation; plastic deformation; microstructure; interfaces; electron structure calculations; cermets; sintering; infiltration; cemented carbides; grain boundaries; cutting tools; density-functional theory; hardmetals; WC-Co; wetting;

    Abstract : Cemented carbides are hard composite materials of great technological importance. They are widely used as tool materials in a large variety of applications where the demands on hardness and toughness are high, including e.g.≈mining, turning, cutting, and milling. READ MORE
