  1. 16. Fabrication of a light-weight SOFC using ceramic fibre paper as substrate

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Philip Löfkvist; [2015]
    Keywords : inorganic chemistry; solid oxide fuel cell; unmanned aerial vehicle; high temperature heat treatment; yttria stabilized zirconia; ceramic fibre paper; catator; nickel oxide; impregnation; paste manufacturing; ultra-sonication; ball-milling; optical microscopy; materials chemistry; scanning electron microscopy; materialkemi; Technology and Engineering;

    Abstract : A novel method for the fabrication of a light-weight solid oxide fuel cell (SOFC) has been evaluated at Catator. This was conducted in order to lower the weight and thus cost of an unmanned aerial vehicle. The main aim for this thesis was to achieve a thin, dense and crack-free electrolyte using a ceramic fibre paper as substrate. READ MORE

  3. 17. Spray Parameters Influence on Suspension Plasma Sprayed Zirconia coatings properties

    University essay from Högskolan Väst/Avd för tillverkningsprocesser

    Author : Tao Ru; [2014]
    Keywords : SPS; parameters; zirconia; properties;

    Abstract : Thermal barrier coatings (TBCs) are a simple and proven method to protect hot section components. Suspension Plasma Spray (SPS), an emerging process technology to generate TBCs, compared with traditional Atmospheric Plasma Spray APS, can deposit thinner coat-ings with finer microstructure.

  4. 18. Effect of Veneering Dental Zirconia on Bond Strength. A pilot study

    University essay from Umeå universitet/Tandläkarutbildning

    Author : Ali Habib; Zaid Al-Khateeb; [2014]
    Keywords : ;

    Abstract : The objective of the study was to evaluate the effect of veneering zirconia surfaces with feldspar-based ceramics or glass ceramics on bond strength when using a resin composite cement. Forty-eight ytteria tetragonal zirconia polycrystal (Y-TZP) specimens were randomly divided into four groups. READ MORE

  5. 19. Thermal barrier coatings for diesel engine exhaust applications

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

    Author : Christoffer Blomqvist; [2014]
    Keywords : TBC; thermal barrier coatings; APS; mullite; YSZ;

    Abstract : The strive to increase the engine efficiency in terms of fuel consumption and lower emissions have lead to higher demands on materials. In this thesis five different thermal barrier coatings applied using air plasma spraying to three materials commonly used for exhaust application are evaluated. READ MORE

  6. 20. Implant-supported zirconia-based fixed dental prostheses - a literature review

    University essay from Malmö högskola/Odontologiska fakulteten (OD)

    Author : Hannah Fransson; [2014]
    Keywords : fixed dental prostheses; implant-supported; zirconia; Y-TZP;

    Abstract : Det ökade intresset av keramiska material har främst centrerat kring zirkoniabaserade keramer på sistone. Zirkoniabaserade fastsittande broar är ämne för en pågående diskussion. Det finns några få publicerade studier på ämnet men med varierande kvalitet och det finns ingen sammanställning av implantatstödda zirkoniabaserade broar. READ MORE
