  1. 1. Pilot Study: Test Rig for Self-lubricating Kaplan Runner Bearings

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

    Författare :Bhairav Khadke; [2023]
    Nyckelord :Hydropower; Kaplan turbine; Self-lubricating bearing Test rig. Hydropower; Kaplan turbine; Self-lubricating bearing Test rig.; Vattenkraft; Kaplanturbin; Självsmörjande lager Testrigg.;

    Sammanfattning : Hydropower has a relatively small impact on the climate and contributes to almost half of Sweden’s electricity production. Vattenfall own and operate roughly 125 large scale hydro power units of which about half utilizes a Kaplan turbine. LÄS MER

  3. 2. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant

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

    Författare :Cecilia Nemeth; [2020]
    Nyckelord :high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

    Sammanfattning : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. LÄS MER

  4. 3. Friction and Wear Performance of Experimentally Developed Self-lubricating PPS/PTFE Composites

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

    Författare :Kimberly Rose Lagrama; [2019]
    Nyckelord :PPS; PTFE; self-lubricating composites;

    Sammanfattning : Demanding applications, as well as the push to eliminate the need for fossil-fuel based lubricants, create the need for the development of high-performance polymers. Polyphenylene Sulfide (PPS) is an example of a high-performance polymer and has a high service temperature, good dimensional stability, and excellent chemical resistance. LÄS MER

  5. 4. Enabling More Efficient E-Mobility : Grease Development by a Novel Bearing-Grease Test Machine

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Gabriel Benjamin Calderon Salmeron; [2019]
    Nyckelord :Deep groove ball bearing; Lithium complex grease; Polypropylene grease; energysaving potential; High speed bearing-grease testing machine; Spårkullager; Litiumkomplexfett; Polypropenfett; Energibesparingspotential; Höghastighetslagermaskin;

    Sammanfattning : The inclusion of electric vehicles in the automotive industry represents an opportunity for lubricating grease producers. Different speed, loads, and electric conditions are present in the bearings of the electric vehicles when compared with the conditions in a traditional internal combustion engine vehicle. LÄS MER

  7. 5. Self-Lubricating Properties of Laser Claddings for High Temperature Forming Processes

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

    Författare :Tugce Caykara; [2018]
    Nyckelord :self-lubricating; steel; aluminium; friction; wear; high temperature; hot forming;

    Sammanfattning : This thesis summarizes the work done on tribological characterization of multifunctional hardfacing coatings with self-lubricating properties, intended for use in mechanical components operating in high temperature applications for which conventional lubricants are no longer effective. Deposition techniques like laser cladding have a great potential in reworking/repair of high value industrial components in order to extend their lifetime. LÄS MER
