  1. 6. Tailoring of Transition Metal Silicides as Protective Thin Films on Austenitic Stainless Steel

    Författare :Eric Tam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Rockwell-C adhesion test; X-ray diffractrometry XRD ; Pretorius’ effective heat of formation EHF model; Ion-beam sputter deposition IBSD ; Reciprocating sliding wear test; Corrosion; Stainless steels; Thin films; Tribology; Transition metal silicides; X-ray photoelectron spectroscopy XPS ; Potentiodynamic polarisation measurements;

    Sammanfattning : The objective of this study is to make use of transition metal silicides in a novel way as protective thin films on engineering metals. It can then be possible to take advantage of the potentially good corrosion resistance of metal silicides while compensating for their brittle nature by the ductile bulk material. LÄS MER

    Författare :Salim Ghandour; Cecilia Persson; Donal McNally; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Topology Optimization; Spine; Intervertebral Disc; Papain; Additive Manufacturing; Biomechanics; Bone Cement; PMMA; Calcium Phosphate; Cage; Fusion; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

    Sammanfattning : The overarching objective of this thesis was to develop intervertebral implants for degenerated discs through design, fabrication, and mechanical validation. The research had four primary aims, each addressing different facets of implant development. LÄS MER

  4. 8. Imaging and analysis methods for automated weld inspection

    Författare :Patrik Broberg; Tadeusz Stepinski; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Welding; materials; Manufacturing and materials engineering; Produktions- och materialteknik; Experimental Mechanics;

    Sammanfattning : All welding processes can give rise to defects, which weakens the joint and can eventually lead to the failure of the welded structure. In order to inspect welds for detects, without affecting the usability of the product, non-destructive testing (NDT) is needed. LÄS MER

  5. 9. Optimisation of Railway Switches and Crossings

    Författare :Björn Pålsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel and rail wear; railway turnout; optimisation; switch crossing; dynamic vehicle-turnout interaction;

    Sammanfattning : Methods for simulation-based optimisation of the design of railway turnouts (switches & crossings, S&C) are developed and demonstrated. Building on knowledge of dynamic wheel–rail interaction in turnouts, it is investigated how rail profile degradation can be reduced by the optimisation of geometry and component stiffness of the track superstructure.

  7. 10. Mixed mode loaded adhesive layers : from measurement of material data to analysis of structural behaviour

    Författare :Jia Li Högberg; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; mixed mode testing; cohesive law; J-integral; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Sammanfattning : In manufacturing of multi-material products, a joining method that is able to cost-effectively assemble components made of dissimilar and similar material, with irregular geometries, is optimal. As an alternative, adhesive bonding is in-creasingly adapted by the industry, which is also used in manufacturing of multi-phase materials. LÄS MER
