  1. 6. Tin-based Glasses: Structure and Electrochemical Properties

    Författare :Cecilia Gejke; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion battery; anode; borate glasses; phosphate glasses; tin; reverse Monte Carlo simulation; Raman spectroscopy; infrared spectroscopy; neutron diffraction;

    Sammanfattning : This thesis presents an investigation of microscopic structure and electrochemical properties, and their relationship, for various tin-based borate, phosphate and borophosphate glasses. Tin-based glasses have attracted a lot of scientific interest as anode materials in Li-ion batteries. LÄS MER

  3. 7. High-resolution characterization of TiN diffusion barrier layers

    Författare :Marlene Mühlbacher; Lars Hultman; Christian Mitterer; Lars Johnson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; TiN; Microstructure; Transmission electron microscopy; TEM; Atom probe tomography; APT;

    Sammanfattning : Titanium nitride (TiN) films are widely applied as diffusion barrier layers in microelectronic devices. The continued miniaturization of such devices not only poses new challenges to material systems design, but also puts high demands on characterization techniques. LÄS MER

  4. 8. Microstructural investigation of CVD TiAlN, TiN and WN coatings

    Författare :Ren Qiu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEM; XEDS; TiN; SEM; APT; TiAlN; coating growth; EBSD; WN; CVD;

    Sammanfattning : High speed machining of workpiece materials puts extreme thermal and pressure loads onto the cutting tool inserts, which thus must possess both high hardness and good toughness. Nowadays, most cutting tools are made of cemented carbide substrates that are coated with wear-resistant coatings. LÄS MER

  5. 9. Tin whiskers: experiments and modelling

    Författare :Johan Hektor; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tin whiskers; Intermetallics; Phase field models; X-Ray Diffraction;

    Sammanfattning : Tin whiskers are hair-like single crystals that spontaneously grow from tin-coated surfaces. Whiskers are commonly found in electronic components, where tin coatings are used in, e.g., soldering applications, and to protect components from corrosion. LÄS MER

  7. 10. Electrical and Frictional Performance of Tin-Coated Contacts Exposed to Wear and Fretting Corrosion

    Författare :Tag Hammam; Åke Öberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Friction; Fretting; Wear; Contact resistance; Tin; Connectors; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The complexity of electronic systems in vehicles is rapidly increasing, and as a consequence, the long-term reliability of automotive connectors has become an important issue. The aims of this thesis have been: 1. to characterize the friction, wear and electrical properties of tin coatings, 2. LÄS MER
