   Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Författare :Viktor Lange; [2023]
   Nyckelord :Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

   Sammanfattning : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. LÄS MER

3. 2. Lubricants impact on cutting forces - Torque reduction in tapping process

   Master-uppsats, KTH/Industriell produktion

   Författare :Marco MANGIATERRA; [2018]
   Nyckelord :Lubricant; Broaching; Cutting Fluid; Tapping; Torque; Smörjning; brotschning; skärvätskor; tappning; vridmoment;

   Sammanfattning : Bearbetningsprocesser är en viktig del av tillverkningsindustrin. Dessa företag måste kontinuerligt förbättra sina processer och göra dem mer effektiva, minska de ekologiska fotavtrycken och driftskostnaderna. Syftet med denna rapport är att förbättra en rund brotschningsprocess för ett bilföretag. LÄS MER

4. 3. Tribological studies on multifunctional hardfacings for friction control at high temperatures

   Master-uppsats, Luleå tekniska universitet/Maskinelement

   Författare :Todor Vuchkov; [2017]
   Nyckelord :high temperature tribology; laser cladding; solid lubricants;

   Sammanfattning : 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. LÄS MER

5. 4. Self Lubricating Components

   Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

   Författare :Simon Tidén; Niklas Levin Bjärnlid; Tim Melin; Daniéla Quist; Filip Selenius Larsson; [2017]
   Nyckelord :self lubricating; solid lubricant; high speed steel; powder metallurgy; friction; wear; molybdenum disulfide; tungsten disulfide; hexagonal boron nitride; soft metals; copper;

   Sammanfattning : The tribological and mechanical properties are of great importance for a material’s lifetime, since it is highly dependent on these two factors. The purpose of this report was to examine suitable solid lubricants for Erasteel, a company that manufactures hot isostatic pressed high speed steels, that will enhance the tribological properties of their steels without worsening the mechanical properties.
