1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

   Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

   Författare :Shivang Parmar; [2023]
   Nyckelord :Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

   Sammanfattning : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. LÄS MER

3. 2. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel

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

   Författare :Abderrahim Ait ouakrim; [2023]
   Nyckelord :Metal Matrix Composites MMCs ; Manganese steel; Carbides particles; Wear resistance;

   Sammanfattning : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.

4. 3. Microstructure characteristics and tribological behaviour of plasma sprayed ceramic coatings

   Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

   Författare :Luigi Fadini; [2023]
   Nyckelord :Thermal spray; APS; SPS; tribology; wear resistant ceramic coatings;

   Sammanfattning : Surface engineering is increasingly becoming inevitable for meeting the high-performance requirements constantly expected from modern engineering components. Higher demands for combined functionalities, which a base material alone cannot provide, motivate intensive academic studies on various types of coatings, with the ultimate objective of their practical utilisation in industries.

5. 4. Micro- / Meso- Scale Dielectric Strength Testing of Fibre Composites

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Johannes Fernberg; [2022]
   Nyckelord :Dielectric strength; composite; GFRP; glassfibre; composite microstructure; FEA; electric breakdown; single fibre;

   Sammanfattning : Glass fibre composites are common materials used in high voltage applications as insulating materials that provide good structural integrity. The aim of this thesis is to develop a method of studying the failure in such materials by measuring the dielectric strength on micro- and meso- scale samples, consisting of single fibre filaments and fibre bundles respectively embedded in epoxy resin.

7. 5. The Investigation of Crack Propagation in Cortical Bone using a Phase Field Fracture Approach

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Olivia Karlsson; [2022]
   Nyckelord :Cortical Bone; Cortical bone microstructure; Phase field; Phase field fracture approach; Crack propagation; Technology and Engineering;

   Sammanfattning : Human cortical bone tissue is a complex and strong composite material, with the ability to resist damage via slowing, stopping or redirecting propagating cracks. However, the ability is impaired with age. At the microscale, changes are seen both in terms of increased porosity and as changes in local material parameters. LÄS MER
