  1. 1. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants

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

    Författare :Zapata Tamayo Juan Guillermo; [2021]
    Nyckelord :micropitting; mild sliding wear; surface coating; diamond-like carbon DLC; glycerol-based lubrication; green lubricant; rolling contact fatigue; rolling-sliding;

    Sammanfattning : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.

  3. 2. Study of Fluorescence Dye for Tracing Lubrication Oil inside Marine Engines

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :David Sanned; [2017]
    Nyckelord :Laser Induced Fluorecence; Lubrition Oil; Marine Engines; Flourescence Dye; Technology and Engineering; Physics and Astronomy;

    Sammanfattning : Engine lubrication is very important for engine sustainability and efficiency. It becomes even more important when heavier fuel types who contributes to lubrication are changed to alternative fuel without the same lubrication abilities. LÄS MER

  4. 3. Graphene as an aqueous Lubricant

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Sammanfattning : The possible use of graphene and its derivatives dissolved in water as a green lubricant is an interesting avenue of research from tribological perspective. In this study, a highly concentrated stock solution of aqueous Graphene employing Polyethylene Glycol(PEG) as surfactant was diluted using proportionate volumes of De-Ionized (D.I. LÄS MER
