  1. 16. Method development for a tribological diffusion couple of rock and cemented carbide

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Alma Fjällström; [2021]
    Nyckelord :Diffusion couple; tribology; cemented carbide; rock; granite; sandstone; Silicon; rock drilling;

    Sammanfattning : In a diffusion couple, the intimacy of the contact between the two parts is of high importance for the results. In a tribological contact, matter can transfer from one part to another and a very intimate contact is formed. LÄS MER

  3. 17. Feasibility of Enhanced Geothermal Systems in the Precambrian crystalline basement in SW Scania, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Hanna Kervall; [2021]
    Nyckelord :EGS; deep drilling; geothermal; petrology; petrophysical properties; Sveconorwegian; Earth and Environmental Sciences;

    Sammanfattning : The ability to evaluate the geothermal potential at a depth of five to six kilometres in the crystalline bedrock is crucial for the EGS-technology to be utilized in the future. This work focuses primarily on presenting expected geological conditions at great depths in southwestern Scania. The study is based on information from E. LÄS MER
