    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. Resistance Element Welding of Ultra High Strength Steel to Aluminium

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Malte Eriksson; [2023]
    Nyckelord :;

    Sammanfattning : The automotive industry strives towards decreased vehicle weight in order to decrease green house gas emissions. To create lighter vehicles, new lighter materials need to be implemented. One issue with new materials is that the traditional joining methods in many cases meet their limitations. LÄS MER

  7. 5. Projection Nut Welding to High- and Ultra-high Strength Steels

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Love Englund; [2023]
    Nyckelord :mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

    Sammanfattning : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. LÄS MER
