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. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

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

   Author : Pranay Kumar Parsi; [2023]
   Keywords : Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

   Abstract : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. READ MORE

4. 3. SFEER Hydrogen Permeation : Finding a suitable coating for the PA6 liner

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Elsa Friis; Klara Karlsson; Rebecka Damgren; Emma Åkesson; Malin Johansson; [2023]
   Keywords : Hydrogen permeation; PA6; coating; hydrogen permeation barrier; polymer hydrogen permeation; permeation; protective coating; hydrogen embrittlement;

   Abstract : Water Stuff & Sun are developing a hydrogen battery based on a technology called SFEER’s. The SFEER’s are spherical high-pressure gas storage containers that are the size of a tennis ball. They consist of a carbon fiber-shell that is lined on the inside with a polymer called PA6.

5. 4. Relating Process Data to Product Quality in Transmission Manufacturing

   University essay from KTH/Industriell produktion

   Author : Claudia Tensi; [2021]
   Keywords : ;

   Abstract : Research has shown that vibration produced by a machine tool provides useful information for the maintenance of its structural parts. Thus, the vibration signal should also give information about tool wear and, consequently, surface roughness of the machined workpieces. READ MORE

6. 5. Analysis of Heating Processes for the Production of Bipolar Plates in PEM Fuel Cells

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : LASSE MATTHIAS REINPOLD; [2020]
   Keywords : ;

   Abstract : Polymer electrolyte membrane fuel cells (PEMFCs) are a promising alternative to combustion engines and batteries in vehicles. PEMFCs are more efficient than combustion engines, and cars powered by PEMFCs tend to have longer ranges than battery powered cars and has a short fuelling time. READ MORE
