  1. 1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ahsan Ali; [2023]
    Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

  3. 2. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Alfred Norberg; [2023]
    Nyckelord :Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

    Sammanfattning : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. LÄS MER

  4. 3. Investigation of high temperature stability of additive manufactured austenitic stainless steels for space applications

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Materialvetenskap

    Författare :Belén Alonso Rancurel; [2023]
    Nyckelord :austenitic stainless steel; additive manufacturing; high temperature corrosion; high temperature stability;

    Sammanfattning : Additive manufacturing (AM) techniques are being studied for their application in the aerospace industry. Numerous benefits come from the already in shape final piece, which needs reduced amount of prime material for its production and can have its shape numerically optimized for weight reduction.

  5. 4. Indragningsmekanism för bensin-och dieselpumpar

    M1-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Felix Gustavsson; Alfred Stoltz; [2022]
    Nyckelord :Hose retraction mechanism; Slangindragningsmekanism;

    Sammanfattning : This thesis is produced in association with the company Dover Fueling Solutions, DFS, that is working towards the goal of developing ideas and solutions to optimize every aspect of the fueling process for vehicle fuel. A recurring problem is that the fuel hose from truck dispensers are left on the ground after being used. LÄS MER

  7. 5. Utredning av sprickorsakerna i infästningarna till kylelement

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Ammie Bäckström; Nicklas Werner; [2021]
    Nyckelord :;

    Sammanfattning : The assignment handed out by Cementa in Skövde is to investigate why crack formation and propagation emerge in the fixed attachment clamps and propose solutions against it. The fixed attachments are part of the cooling element suspension, used in the cement production to cool the material coming out of the oven. LÄS MER
