  1. 1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Viktor Lange; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Use of a multi-parameter sensor for oil degradation monitoring

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Nicolas Gasnier; [2022]
    Keywords : ;

    Abstract : The continuous monitoring in real time of the degradation of lubricants is of great interest for many different industries to optimize the use of lubricating oil in combustion engines. Traditional oil quality diagnostic methods can measure accurately the different levels of oil degradation, but they cannot be implemented on engines to perform continuous oil quality diagnostics.

  4. 3. Phosphonium Ionic Liquids at Interfaces: NR studies of interfacial electro-responsiveness

    University essay from KTH/Kemi

    Author : Filip Mehler; [2022]
    Keywords : Neutron reflectometry; Ionic liquid; Phosphonium Ionic Liquid; Tribology; Neutronreflektometri; Jonvätskor; fosfoniumjonvätskor; tribologi;

    Abstract : Fosfoniumjonvätskor har tidigare studerats som potentiella nya avancerade smörjmedel på grund av sina unika fysikaliska egenskaper och fördelar jämfört med både traditionella smörjmedel och andra typer av jonvätskor. Dessa studier har uppvisat lovande resultat med avseende på reducering av nötning och friktion såväl som kontroll av dessa parametrar med en pålagd elektrisk potential. READ MORE

  5. 4. Efficiency of Surface Treated Electric Vehicle Gears

    University essay from KTH/Maskinkonstruktion (Inst.)

    Abstract : Gears are an important part of many machines. This thesis is a study in how new mechano-chemical surface treatments can be used to improve the efficiency in gear transmissions, specifically those relating to electric vehicles. READ MORE

  6. 5. Iron-catalyzed graphitization of biochar to produce graphitic carbon materials

    University essay from KTH/Materialvetenskap

    Author : Ziyi Shi; [2021]
    Keywords : graphite; biochar; catalyst; catalytic graphitization; grafit; biokol; katalysator; katalytisk grafitisering;

    Abstract : Demand for high-quality graphite is expected to experience an extraordinary growth rate, in large part due to its wide range of industrial applications such as adsorbents, lubricants, electrodes, etc. This thesis developed a novel sustainable approach to produce green-graphite materials by applying biochar, acarbon-rich valuable by-product obtained from biomass, as a carbon precursor.
