  1. 1. Assessment of a Sustainable Water-based Lubricant for Electric Drivelines : Lubrication and Cooling performance of a Water-based Lubricant

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

    Author : Ugo Jantel; [2022]
    Keywords : Water-based Lubricant; Cooling; Driveline;

    Abstract : In recent years, the impact of humans on the environment has been the subject of much debate. Car companies in particular are among the main actors in this environmental degradation with the polluting aspect of combustion cars. READ MORE

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

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

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

    Abstract : 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. 3. Tribology of newly developed EAL versus water in hydropower turbine bearings

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

    Author : Nayan Dhakal; [2019]
    Keywords : water-based lubrication; hydropower; turbine bearings; environmentally adaptive lubricants; modified water; viscosity modifiers; polyvinylpyrrolidone; poly sodium 4-styrenesulfonate ; UHMWPE; wear;

    Abstract : The increasing demand for more readily bio-degradable, renewable and non-toxic environmentally adaptive lubricants with a lower degree of bioaccumulation has escalated the investigation of water-based lubricants as the potential alternatives for conventional mineral-based oils. Water is an excellent environmentally adapted lubricant; however, it is a low viscous fluid and holds downsides of having corrosive nature and extremely low pressure-viscosity coefficient leading to insufficient load-carrying capacity.

  4. 4. Spectroscopic evaluation of stability and homogeneity of formulated lubricant

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Amir Vranjkovina; [2019]
    Keywords : Lubricants; Base oil; ICP-AES; FTIR; Method validation; Smörjmedel; Basoljor; ICP-AES; FTIR; Metodvalidering;

    Abstract : Lubricant is a common name for a large group of products that are essential for almost every engine or other machinery equipment that include mechanical part movements. Their main application is reduction of the friction between two rubbing surfaces by interposing a lubricating film between them. READ MORE

  5. 5. Bronze-Steel Friction Characteristics under the Lubrication of Modified Water/Glycerol Mixtures

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

    Author : Karim Hamouda; [2017]
    Keywords : Glycerol; glycerol additives; stick-slip; shudder; friction modifiers;

    Abstract : Increasing environmental awareness has driven a lot of research to look into various environmentally friendly lubricants which can replace more conventional mineral oil based lubricants. This is true in particular for marine and hydropower applications where the risk of lubricant leakage can be damaging to the local environment. READ MORE
