  1. 1. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys

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

    Författare :Rabia Arshad; [2022]
    Nyckelord :Hot forming of aluminium; friction; high temperature lubrication; strip draw; wear.;

    Sammanfattning : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. LÄS MER

  3. 2. A Pre-Assessment related to Refractory Waste Management in Sweden : Pre-study of the performance of MgO-C bricks made from recycled MgO-C refractory materials for use in steel production

    Master-uppsats, KTH/Materialvetenskap

    Författare :Pranav Jagtap; [2021]
    Nyckelord :MgO-C brick; Refractory; Recycling; Reusing; Swedish Steel industries; MgO-C tegel; Eldfast; Återvinning; Återanvändning; Svensk stålindustri;

    Sammanfattning : Steel industries consume refractory materials on a large scale. High temperature resistant refractory materials are essential for linings of the steelmaking vessels, to protect them from corrosive environments, high temperatures, molten steels and slags during transportation and steelmaking operations.

  4. 3. Barrier properties of model coatings using recycled iron oxide pigment

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Nathalie Hagenfjärd; [2021]
    Nyckelord :Organic coatings; Iron oxide pigment; EIS; Barrier properties;

    Sammanfattning : The aim of this study was to compare the barrier properties of organic coatings with the same polymer matrix but different types of iron oxide particles, commercial and recycled. The work was carried out for the company SSAB with the aim of investigating whether the pigment Merox ferric oxide, which is produced in-house at the company during the pickling process, can be used and replace commercial iron oxide pigment.

  5. 4. Identifying risks of AdBlue spray on stainless steel surfaces

    Master-uppsats, KTH/Kemiteknik

    Författare :Evelina Tvinne Flyg; [2021]
    Nyckelord :Urea; Stainless steel; SCR; Deposit; Corrosion; Urea; rostfritt stål; SCR; Avlagring; Korrosion;

    Sammanfattning : Utsläppskontroll, reglerad av allt strängare lagstiftning, ställer höga krav på utvecklingen av noggranna efterbehandlingssystem för avgaser. När det gäller utsläpp från dieselmotorer utgör NOx-minskning en av de största utmaningarna. För tunga fordon tacklas denna utmaning ofta genom ett SCR-system. LÄS MER

  7. 5. Understanding the effect of material composition and microstructure on the hot corrosion behaviour of plasma sprayed thermal barrier coatings

    Magister-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Författare :Ehsan Najafi; [2019]
    Nyckelord :Thermal barrier coatings; molten salt infiltration; TBC variations; hot corrosion test;

    Sammanfattning : Thermal barrier coatings (TBC) are used in the hot sections of gas turbine engine in order to insulate the substrate at high temperature. Molten salt infiltration retards the durability of TBCs. The current standard material, i.e. LÄS MER
