  3. 2. Studie av syretillgångens inverkan på nötning av hårdmetall vid bearbetning av kopparlegeringar

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

    Författare :Julia Rosengren; [2023]
    Nyckelord :tribologi; nötning; hårdmetall; mässing;

    Sammanfattning : During the production of metal zippers, cemented carbide (CC) tools are used to cut preformed brass wire into small elements. Even though the cemented carbide is much harder than the copper alloy, it gets worn and eventually the tool must be replaced. LÄS MER

  4. 3. Modeling of a ball contact with a coated plate

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

    Nyckelord :Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Sammanfattning : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. LÄS MER

  5. 4. Test Rig to Measure the Coefficient of Friction of Various Materials at Different Velocities and Pressures

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