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

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

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

    Abstract : 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. READ MORE

  3. 2. Mapping and characterisation of surface damage and wear mechanisms in gun barrels : Gun barrels exposed to cyclic thermo-mechanical loading

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Martin Perkovic; [2020]
    Keywords : Wear; erosion; sliding wear; gun barrel; characterisation;

    Abstract : Gun barrels are an important component in advanced defence systems. The gun barrels are used for direct and indirect fire and the material of the gun barrel is exposed to great strains and high temperatures. This sets high demands on the material of the gun barrel. During firing the gun barrel can be damaged. READ MORE

  4. 3. Polymer Aging Mechanics : An investigation on a Thermoset Polymer used in the Exterior Structure of a Heavy-duty Vehicle

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Basil Abu-Ragheef; [2019]
    Keywords : polyDicyclopentadiene; aging; thermosets; fatigue; mechanical properties; thermal fatigue; digital image correlation; viscoelasticity; polymer degradation; thermo-oxidation; photo-oxidation;

    Abstract : The use of plastic materials in the design of vehicle components is primarily driven by the need for vehicle weight and cost reduction. Additionally, these materials give design engineers freedom in creating appealing exterior designs. READ MORE

  5. 4. Influence of Nitrocarburization on Thermo-Mechanical Fatigue Properties : Material Characterization of Ductile Cast Iron for Exhaust Components

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Wännman Sofia; [2018]
    Keywords : Ductile cast iron; Nitrocarburizing; Thermo-mechanical fatigue;

    Abstract : The large number of vehicles operating on the roads cause high emissions and consequently a negative effect on the environment. When developing and optimizing internal combustion engines, certain requirements must be considered, which are environmental regulations, reduced fuel consumption and increased specific power.

  6. 5. Failure analysis of suspension plasma sprayed thermal barrier coatings

    University essay from Högskolan Väst/Forskningsmiljön produktionsteknik(PTW)

    Author : Mohammed Jasim; [2017]
    Keywords : Failure analysis; Suspension plasma sprayed; Thermal barrier coating;

    Abstract : Thermal barrier coatings (TBC) are proven to protect the hot section of components operated under elevated temperature. Suspension Plasma Spray (SPS) is an emerging manufacturing process that is used to produce TBCsI, It has the ability to deposit a thinner TBC that has finer microstructure than coatings deposited using traditional Atmospheric Plasma Spray (APS).
