    Författare :Lisa Rullik; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminum alloy; brazing; AA 6063; duplex stainless steel; SAF 2507; XPS; APXPS; XPEEM; XRR; microstructure; aluminiumlegering; hårdlödning; AA 6063; duplexstål; SAF 2507; XPS; APXPS; XPEEM; XRR; mikrostruktur;

    Sammanfattning : This thesis reports on surface studies of industrial materials whose importance for society manifests in the vast range of applications. In industrial materials alloying is performed in order to improve the parent material's physical and mechanical properties such as strength, corrosion and wear resistance, as well as high temperature performance in comparison to the pure metal.

  4. 3. Controlling infiltration when brazing P/M parts and during manufacture of aluminium metal matrix composites

    Författare :Esa Vuorinen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Sammanfattning : Infiltration is used in the production of several different material groups as electric contact materials, copper infiltrated sintered steels and metal matrix composites. The mechanism of infiltration causes also unwanted difficulties in processing as brazing of porous sintered compacts. LÄS MER

  5. 4. Adhesion strength of HVOF sprayed Inconel 718 coatings

    Författare :Christophe Lyphout; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion Strength; Residual Stress; Inconel 718; Thermal spray; Finite Element Method; HVOF; High Velocity Oxy-Fuel;

    Sammanfattning : 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. LÄS MER

  7. 5. Accelerators for Physics Experiments : From Diagnostics and Control to Design

    Författare :Elena Wildner; Thomas Lindblad; Mikael Eriksson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astroparticle physics; Astropartikelfysik;

    Sammanfattning : This thesis develops techniques of control-methods, optimization, and diagnostics of accelerator equipment and the produced particle beams with emphasis on the Large Hadron Collider (LHC) project at CERN. From a solid knowledge of the characteristics of the manufactured accelerator equipment gained from in-depth measurements and analysis of measured data, a link to an enhanced equipment design can be made.
