  1. 1. Cathodic arc deposition of metal-rich Cr-based coatings

    Författare :Johan Nyman; Hans Högberg; Jens Birch; Niklas Sarius; Muhammad Junaid; Nina Schalk; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cathodic arc deposition; Cr coatings; Metal-rich; Cr-N; Cr-C;

    Sammanfattning : Wood and wood-based products have always been key components in the development of human civilization. Nowadays most wood harvesting is done using chainsaws, and their efficient operation helps promote worker safety and reduce emissions. LÄS MER

  3. 2. Improved Oxidation Resistance and Reduced Cr Vaporization from Thin-Film Coated Solid Oxide Fuel Cell Interconnects

    Författare :Hannes Falk Windisch; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 18O-Tracer exposure; Reactive Element; Coating; SOFC; Cr Vaporization; Interconnect; Corrosion;

    Sammanfattning : High electrical efficiency, clean emissions, and the possibility to operate on a great variety of fuels, such as hydrogen, alcohols and hydrocarbons are some advantages of Solid Oxide Fuel Cell (SOFC) technology. Too short lifetimes and high production costs have, however, limited the commercialization of this technology. LÄS MER

  4. 3. Cold spray Cr-coated Optimized ZIRLO claddings: an option for accident tolerant fuels

    Författare :Andrea Fazi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cr coating; atom probe tomography; cold spray; accident tolerant fuel;

    Sammanfattning : Accident tolerant fuel development has started with the aim of providing nuclear fuels able to endure severe accident conditions. Research in this field has also sparked a wave of material renewal in the nuclear industry that had being delayed for the last few decades. LÄS MER

  5. 4. Workpiece steels protecting cutting tools from wear : A study of the effects of alloying elements on material transfer and coating damage mechanisms

    Författare :Toshiharu Aiso; Staffan Jacobson; Urban Wiklund; Staffan Söderberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal cutting; Steel; Cutting tools; Transfer; Coating; Sliding; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : The vision of this thesis is to improve the machinability of workpiece steels. Workpiece material frequently transfers to the cutting tools during machining, and the transfer layers then forming on the tools may give both good and bad effects on machining performance and tool life.

  7. 5. Synthesis and Characterization of Amorphous Carbide-based Thin Films

    Författare :Matilda Folkenant; Ulf Jansson; Erik Lewin; Paul Mayrhofer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amorphous; coating; thin film; nanocomposite; sputter deposition; PVD; XPS; SEM; TEM; electrical properties; mechanical properties;

    Sammanfattning : In this thesis, research on synthesis, structure and characterization of amorphous carbide-based thin films is presented. Crystalline and nanocomposite carbide films can exhibit properties such as high electrical conductivity, high hardness and low friction and wear. LÄS MER
