  1. 1. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Johan Ranstad; [2023]
    Nyckelord :Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Sammanfattning : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. LÄS MER

  3. 2. New design and construction of hightemperature tribology testingequipment : in the context of hard coatings

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Atle Andersson Nykvist; [2023]
    Nyckelord :Tribology; friction; wear; hot wear; hot wear tester; design; construction; tribometer; tribo tester; tribo-tester; Tribologi; friktion; nötning; varmnötning; varmnötare; design; konstruktion; tribometer; tribotest;

    Sammanfattning : There are two main goals of this thesis. Firstly, to improve and develop an existing hot weartester at Karlstad University so that it may test more samples of different sizes. Secondly, totest previously impossible samples and investigate their tribological properties and measurethe coefficient of friction with high reproducibility. LÄS MER

  4. 3. Catenary action to prevent progressive collapse in multistorey timber buildings : An experimental study of tube joints

    Master-uppsats, Luleå tekniska universitet/Träteknik; Luleå tekniska universitet/Institutionen för tillämpad fysik, maskin- och materialteknik

    Författare :Sivert Knutsen; [2023]
    Nyckelord :wood; engineering; construction; massive timber; tube joints; Progressive collapse;

    Sammanfattning : In the modern building industry wood as a building material has been looked on as one of the solutions to lower the environmentally impact of the building industry. Building types that normally have been reserved for concrete and steel are today being built with wood as main load bearing component. LÄS MER

  7. 5. Adhesive bonding of fiber laminate patch to sandwich-structured composite

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Daniel Nesic; [2022]
    Nyckelord :Adhesive bonding; Shipbuilding; Composite construction; Finite element method in structural mechanics; Fiber reinforced plastics; Optical microscopy analysis; Fractography; Technology and Engineering;

    Sammanfattning : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. LÄS MER
