1. 1. 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. 2. Termisk cyklisk utmattning studie av Gd2Zr2O7 / YSZ flerskikts termiska barriärbeläggningar

   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
