  1. 1. 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.

  2. 2. Isothermal Oxidation Study of Gd2Zr2O7/YSZ Multi-Layered Thermal Barrier Coatings

    Magister-uppsats, Högskolan Väst/Avd för tillverkningsprocesser

    Författare :Ran Li; [2015]
    Nyckelord :Multi-layered thermal barrier coating; isothermal oxidation; suspension plasma spray;

    Sammanfattning : Conventional yttria stabilized zirconia (YSZ) are widely used in the gas turbine to protect the substrate material from high temperature. But the common YSZ top coatings have limitations at higher temperature (above 1200 ℃) due to significant phase transformation and intensified sintering effect. LÄS MER

  3. 3. Termisk cyklisk utmattning studie av Gd2Zr2O7 / YSZ flerskikts termiska barriärbeläggningar

    Magister-uppsats, Högskolan Väst/Avd för tillverkningsprocesser

    Författare :Naga Sai Pavan Rahul Gokavarapu; [2015]
    Nyckelord :Thermal barrier coatings; suspension plasma spraying; thermal cyclic fatigue life; yttria stabilized zirconate YSZ ; gadolinium zirconate GZ ;

    Sammanfattning : From many years YSZ is used as the top coat material for TBC's, as it has good phase stability up to 1200°C, higher fracture toughness, lower thermal conductivity, erosion resistance & higher coefficient of thermal expansion. But, it has a drawbacks at high temperature such as sintering and transformation of phases. LÄS MER

  4. 4. Spray Parameters Influence on Suspension Plasma Sprayed Zirconia coatings properties

    Magister-uppsats, Högskolan Väst/Avd för tillverkningsprocesser

    Författare :Tao Ru; [2014]
    Nyckelord :SPS; parameters; zirconia; properties;

    Sammanfattning : 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.
