1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

2. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER
3. FE Simulation of protective insulation of catalysts in exhaust after-treatment systems of trucks and buses : Investigation and characterization of catalytic converter support mat material for accurate modeling in finite element simulations
Master-uppsats,Sammanfattning : The increase of new and ever more stringent emission legislation has brought about with it a surge in the demand for more sustainable automotive solutions. This has particularly been the case for automobiles, including heavy-duty vehicles like trucks and buses, with internal combustion engines, which now require the design and manufacturing of more durable and reliable components.

4. Development of a System to Quantify Coking in Rocket Nozzle Cooling Channels
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Liquid methane is becoming an increasingly attractive rocket propellant due to its high performance characteristics and potential to support in-situ resource utilisation. Methane, however, when heated, can thermally decompose in a process known as pyrolysis. LÄS MER
5. Analys av pressresultat vid pressning av ventilstyrningar i cylinderhuvudet : Analysis of press result when pressing valve guides in the cylinder head
Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskapSammanfattning : Examensarbetet har genomförts i samarbete med Aurobay som tillverkar förbränningsmotorer till personbilar. Studien är kopplad till processen där cylinderhuvudet bearbetas och förbereds inför montering. Problematiken som arbetet berörde var pressningen av ventilstyrningar och ventilsäten i cylinderhuvudet.
