  1. 1. Understanding the effect of material composition and microstructure on the hot corrosion behaviour of plasma sprayed thermal barrier coatings

    University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Author : Ehsan Najafi; [2019]
    Keywords : Thermal barrier coatings; molten salt infiltration; TBC variations; hot corrosion test;

    Abstract : Thermal barrier coatings (TBC) are used in the hot sections of gas turbine engine in order to insulate the substrate at high temperature. Molten salt infiltration retards the durability of TBCs. The current standard material, i.e. READ MORE

  2. 2. Flexural strength of zirconia after grinding, using diamond burrs, silicon carbide burr and water-cooling

    University essay from Malmö universitet/Odontologiska fakulteten (OD); Malmö universitet/Odontologiska fakulteten (OD)

    Author : Markus Rosensvärd; David Danneker; [2019]
    Keywords : Zirconia; ytzp; grinding; zirconium; aging; Strength;

    Abstract : SyfteSyftet med föreliggande studie är att undersöka om slipning av zirkonia med silikatkarbid, diamant, vattenkylning, höghastighetsturbin och låghastighetshandstycke påverkar böjhållfastheten hos zirkonia.Material och metodFemtio provkroppar av yttriumoxidstabiliserad tetragonal zirkonia framställdes med CAD/CAM.

  3. 3. Shear Strength between a Resin Cement and a Cobalt-Chromium Alloy and Yttria-Stabilized Zirconia

    University essay from Umeå universitet/Institutionen för odontologi; Umeå universitet/Institutionen för odontologi

    Author : Philipé Melki; Ninib Masso; [2018]
    Keywords : Shear strength. Resin cement.;

    Abstract : New trademarks appear on the dental market every year and it is difficult to determine whether they should be used in clinical praxis or not. Numerous studies have been carried out to investigate different types of materials, trying to declare which material is best suited for a certain type of restorations. READ MORE

  4. 4. Phase field modelling of LLZO/LCO cathode-electrolyte interfaces in solid state batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Michele Riva; [2018]
    Keywords : LLZO; LCO; phase; field; phase-field; phasefield; solid; state; solid-state; solidstate; battery; batteries; sintering; model; modelling;

    Abstract : This work describes two phase field models for the simulation of the interface evolution between a LiCoO2 cathode (LCO) and a Li7La3Zr2O12 solid electrolyte (LLZO) in a Li-metal/LLZO/LCO battery during high temperature sintering. In these conditions atomic species tend to diffuse into the opposing material, creating an intermediate layer of mixed composition which resists the movement of lithium ions. READ MORE

  5. 5. Shear Strength Between Adhesive Cement and Yttria-Stabilized-Zirconia and Cobalt-Chrome Alloy With and Without Retentive Holes - an in vitro study

    University essay from Umeå universitet/Institutionen för odontologi; Umeå universitet/Institutionen för odontologi

    Author : Rihan Issa; Nuray Acar; [2017]
    Keywords : shear strength; dental alloys; resin-bonded; chromium alloys; resin cement; zirconium oxide.;

    Abstract : ABSTRACT De-bonding is the most common failure of resin-bonded fixed partial dentures. The aim was to determine if the shear bond strength (SBS) differed between a dental adhesive and a Co-Cr alloy and an yttria-stabilized zirconia (Y-TZP). READ MORE
