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

   Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

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

   Sammanfattning : 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. LÄS MER

3. 2. 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.

4. 3. Failure analysis of suspension plasma sprayed thermal barrier coatings

   Magister-uppsats, Högskolan Väst/Forskningsmiljön produktionsteknik(PTW)

   Författare :Mohammed Jasim; [2017]
   Nyckelord :Failure analysis; Suspension plasma sprayed; Thermal barrier coating;

   Sammanfattning : 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).

5. 4. Skräddad mikrostruktur av gadolinium zirkonat baserade värmebarriärbeläggningar som utsätts för termisk cyklisk utmattning

   Magister-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

   Författare :Cliff Hamatuli; [2017]
   Nyckelord :Suspension Plasma Spray; Gadolinium Zirconate; Thermal cyclic fatigue;

   Sammanfattning : Yttria Stabilized Zirconia (YSZ) is the standard ceramic top coat material used for TBC application. Above 1200°C, issues such as CMAS (Calcium Magnesium Alumino Silicates) infiltration susceptibility, phase instability and high sintering rates limits its long durability. LÄS MER

7. 5. 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
