  2. 1. On Adhesion and Galling in Metal Forming

    Author : Magnus Hanson; Sture Hogmark; Ulf Olofsson; Uppsala universitet; []
    Keywords : Engineering physics; adhesion; galling; dry sliding; stainless steel; vanadium nitride; metal forming; Teknisk fysik;

    Abstract : Metal forming is widely used in the industry to produce cans, tubes, car chassis, rods, wires etc. Forming certain materials such as stainless steel, aluminium and titanium, is often difficult, and problems associated with transfer of work material to the tool material are frequent.

  4. 2. Wear in sheet metal forming

    Author : Anders Gåård; Pavel Krakhmalev; Jens Bergström; Åsa Kassman; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; Sheet metal forming; Galling; Materials science; Teknisk materialvetenskap; 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 press lubricants, in combination with the introduction of high and ultra-high strength sheet materials, continuously increases the demands of the forming tools. READ MORE

  5. 3. 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 : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  6. 4. Surface Engineering in Sheet Metal Forming

    Author : Per Carlsson; Mikael Olsson; Niklas Axén; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Friction; wear; metal coated steel sheet; dry lubricants; galling; PVD coatings; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : In recent years, surface engineering techniques have been developed in order to improve the tribological performance in many industrial applications. In sheet metal forming processes, the usage of liquid lubricants can be decreased by using self lubricated tribo surfaces which will result in more environmentally friendly workshops. READ MORE

  7. 5. The Positive Effect of Nitrogen Alloying of Tool Steels Used in Sheet Metal Forming

    Author : Irma Heikkilä; Staffan Jacobson; Sture Hogmark; Pavel Krakhmalev; Uppsala universitet; []
    Keywords : galling; nitrogen; tool steel; sliding contact; metal forming; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : Sheet metal forming processes are mechanical processes, designed to make products from metal sheet without material removal. These processes are applied extensively by the manufacturing industry to produce commodities such as heat exchangers or panels for automotive applications. They are suitable for production in large volumes. READ MORE
