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)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

2. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

3. A pre-study for functional coatings evaluated on light metals to be applied on a new HPDC Mg-alloy : Investigating tribological and thermophysical properties, as-cast and coated
University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och designAbstract : Magnesium with two-thirds of the density compared to aluminium and one-quarter of steel, intrigues product developers and material scientists due to the light metal’s excellent combination of strength to weight ratio as well as their capability of being produced as a High Pressure Die Cast component compared to other ferrous or light metal alloys. However, a magnesium alloy inherits some concerning drawbacks, limiting the exploitation in structural applications and mechanical design such as automotive, heavy machinery and aerospace components.
