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

   University essay from KTH/Skolan för industriell teknik och management (ITM)

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

   Abstract : 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. READ MORE

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

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

   Abstract : 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. READ MORE

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

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Kimberly Rose Lagrama; [2019]
   Keywords : PPS; PTFE; self-lubricating composites;

   Abstract : 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. READ MORE

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

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

   Abstract : 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. READ MORE

6. 5. Tribological studies on multifunctional hardfacings for friction control at high temperatures

   University essay from Luleå tekniska universitet/Maskinelement

   Author : Todor Vuchkov; [2017]
   Keywords : high temperature tribology; laser cladding; solid lubricants;

   Abstract : Mechanical components operating at elevated temperatures can be identified in the aerospace industry as well as in metal forming. Hot stamping is a metal forming technique utilized for manufacturing high strength lightweight components for the automotive industry. READ MORE
