  6. 4. 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

  7. 5. Self Lubrication on the Atomic Scale : Design, Synthesis and Evaluation of Coatings

    Author : Mattias Lindquist; Sture Hogmark; Urban Wiklund; Ian Hutchings; Uppsala universitet; []
    Keywords : Materials science; Tribology; low friction; PVD; sputtering; nanocomposite; Materialvetenskap;

    Abstract : In this thesis a new design concept of tribologically active coatings aimed for low friction applications, have been explored. Materials modeled by ab initio DFT calculations were realized through deposition of carbide and nanocomposite coatings by DC-magnetron sputtering. READ MORE
