  1. 16. Correlation between microstructure and fatigue cracks in cast aluminium alloy A205

    Kandidat-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Max Holmberg; Pontus Sundberg; [2022]
    Nyckelord :Aluminium Alloy A205;

    Sammanfattning : Materials research in the aerospace industry is, among other things, focused on reducing the weight and increasing the life of components. Materials with high strength and long lifespan are therefore examined. LÄS MER

  3. 17. Abrasionsmekanismer i labtest och fält : Utvärdering av metoder för nötningsprovning av spetsar till pinnkultivatorer

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Clara Landström; [2022]
    Nyckelord :tribologi; materialvetenskap; abrasiv nötning;

    Sammanfattning : In this master thesis two simplified and small-scale methods for two-body and three-body abrasive wear were examined. It was examined how representative the methods were compared to field-tested points in a cultivator for agriculture. A total of six points with different compositions were tested and ranked based on the test results. LÄS MER

  4. 18. Evaluation of different non-metallic inclusions in steel chips by using electrolytic extraction : Evaluation of a methodology for electrolytic extraction and scanning electron microscopy - energy dispersive spectroscopy (SEM-EDS) analysis

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Niklas Jespersson; Torbjörn Sandberg; [2021]
    Nyckelord :;

    Sammanfattning : Analysing non-metallic inclusions (NMI) by conventional microscopy is prone to errors.  Better imaging can be achieved by using electrolytic extraction (EE) to effectively dissolve the metal matrix, freeing the inclusions so that they can be collected on a filter. LÄS MER

  5. 19. Surface Engineering of Bipolar Plates for PEM-Water Electrolysis : Cost-Effective Corrosion Protection

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Tristan Dettke; [2021]
    Nyckelord :Hydrogen; Water Electrolysis; Fuel Cells; Bipolar Plates; Thin Films; Coatings; Impact Coatings; IFM; Tristan Dettke; PEM;

    Sammanfattning : Hydrogen production by PEM-Water electrolysis is an environmentally benign and promising approach to store excess energy from renewable energy sources but facing drawbacks of high costs, mainly due to a harsh cell-environment. The aim of my Master Thesis was to reduce the costs of the most expensive cell component, the bipolar plate by surface engineering. LÄS MER

  7. 20. Characterization of phases in Argon Oxygen Decarburization slag

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Emil Rosqvist; Theodore Vassi; [2021]
    Nyckelord :;

    Sammanfattning : Slag is an important part of steelmaking with the AOD (Argon Oxygen Decarburization) process. In this work the focus was on developing a methodology for characterizing phases in slagsamples obtained after decarburization, reduction and desulphurization. LÄS MER
