    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
