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

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

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

    Abstract : 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. READ MORE

  3. 2. Microstructure characteristics and tribological behaviour of plasma sprayed ceramic coatings

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Luigi Fadini; [2023]
    Keywords : Thermal spray; APS; SPS; tribology; wear resistant ceramic coatings;

    Abstract : 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. Erosion Behaviour of Thermal Barrier Coatings

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : Caroline Wännman; [2021]
    Keywords : erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

    Abstract : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. READ MORE

  5. 4. Development of a multi-collector inductively coupled plasma massspectrometry method for measurement of stable sulphur isotope ratios in aerosol sulphate

    University essay from Uppsala universitet/Analytisk kemi

    Author : Katerina Rodiouchkina; [2018]
    Keywords : Sulphate aerosol; isotope ratio; sulphur isotope; δ34S and δ33S measurements; MC-ICP-MS; method development; inter-laboratory comparison;

    Abstract : Sulphur stable isotope ratios are useful tracers in geological and environmental studies. They can for example be used to trace the origin of atmospheric sulphate aerosols, because anthropogenic sulphate and natural sulphate have distinguishable δ34S-values (δ34S value of approximately +0 to +8 ‰ for anthropogenic and approximately +12 to +19 ‰ for natural).

  6. 5. Failure analysis of suspension plasma sprayed thermal barrier coatings

    University essay from Högskolan Väst/Forskningsmiljön produktionsteknik(PTW)

    Author : Mohammed Jasim; [2017]
    Keywords : Failure analysis; Suspension plasma sprayed; Thermal barrier coating;

    Abstract : 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).
