  1. 1. Feasibility Study on Additive Manufacturing of Copper Windings using Electron Beam Melting

    Master-uppsats, KTH/Produktionsutveckling

    Författare :Marilena Wiele; Murad Abulawi; [2023]
    Nyckelord :Electron beam melting; Additive manufacturing; Electric motor windings; Hairpin windings; Winding design; Copper; Parameter optimization; Electrical conductivity; Elektronstrålesmältning; Additiv tillverkning; Elmotorlindningar; Hårnålslindningar; Lindningsdesign; Koppar; Parameteroptimering; Elektrisk ledningsförmåga;

    Sammanfattning : Within the framework of this thesis, the electron beam melting of pure copper for the purpose of producing electrical windings was examined. The conventional manufacturing process of copper windings was investigated, and the potential advantages offered by the design freedom inherent in the electron beam melting process were explored.

  3. 2. Sputtered Transparent Contact Layers for Bifacial and Tandem Solar Cells

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Klara Kiselman; [2022]
    Nyckelord :Solar cells; ITO; indium doped tin oxide; bifacial cell; tandem cell; transparent conductive oxides;

    Sammanfattning : A key to solar cells with lower environmental impact is higher efficiency and reduced material usages. Bifacial solar cells may have a higher efficiency as light can enter from two directions and tandem solar cells may use a larger part of the incoming solar spectrum, increasing the efficiency.

  4. 3. Omkonstruktion av mekaniskt arm och varmhållningslock till konverterugn : Konverterhallen, Boliden Rönnskär

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Marcus Stenlund; [2022]
    Nyckelord :värmeöverföring; varmhållningslock; lock; energi; förbränning; besparing;

    Sammanfattning : When the copper production takes place, the pure rock smelting undergoes a sub-processcalled copper conversion. This process is a batch process, which means that the converterfurnace cools down before the next refill. Inside the converter ovens there is a masonrywear brick that is adversely affected when exposed to temperature variations. LÄS MER

  7. 5. ADDITIVE MANUFACTURING OF PURE COPPER USING ELECTRON BEAM MELTING (EBM)

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

    Författare :Prithiv Kumar Chinnappan; Vishal Shanmugam; [2022]
    Nyckelord :Additive Manufacturing; Electron Beam Melting; Pure Copper; Process Optimisation.; Additiv tillverkning; Elektronstrålesmältning; Ren koppar; Processoptimering.;

    Sammanfattning : Pure copper (Cu) has the properties of high optical reflectivity and surface tarnishing as well as excellent thermal and electrical conductivity. Accordingly, laser-based additive manufacturing (AM) techniques confront various difficulties to produce thismaterial. LÄS MER
