  1. 6. 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

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

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

    Författare :Mohammadreza Saeedi; [2023]
    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

  4. 8. 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)

    Författare :Prathik Jain Santhilal; [2023]
    Nyckelord :coefficient of friction; machine design; pressure; test rig; tribology; velocity.; friktionskoefficient; maskinkonstruktion; tryck; testrigg; tribologi; hastighet.;

    Sammanfattning : This thesis presents the design and development of a versatile test rig specifically tailored for measuring frictional properties of diverse materials across a wide range of velocities and pressures. The ability to accurately quantify frictional behaviour under varying conditions is essential for understanding material performance in numerous applications, such as automotive, aerospace, and manufacturing industries.

  5. 9. 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

  7. 10. On the friction and failure mechanisms of bearing and gear surfaces lubricated by a novel nanoadditive in highly stressed operating conditions

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

    Författare :Diego Manuel Chamorro Ruz; [2022]
    Nyckelord :micropitting; nanoadditive; gear; bearing; tribology; rolling contact fatigue;

    Sammanfattning : Obtaining an enhanced lifespan for mechanical transmissions has become a challenge in diverse application sectors. Micropitting as a contact fatigue mechanism has seriously jeopardized the well-being of rolling-sliding elements present for instance in gearboxes. LÄS MER
