  3. 7. Thermal Barrier Coatings : Failure Mechanisms and Life Prediction

    Författare :Krishna Praveen Jonnalagadda; Ru Lin Peng; Xin-Hai Li; Robert Eriksson; Nicholls John; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. LÄS MER

  4. 8. Thermal Barrier Coatings : Durability Assessment and Life Prediction

    Författare :Robert Eriksson; Sten Johansson; Michael Schütze; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. LÄS MER

  5. 9. Multilayer Structures for Biomaterial Applications : Biomacromolecule-based Coatings

    Författare :Tobias Halthur; Per M. Claesson; Bjørn Stokke; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multilayer; layer-by-layer deposition; physical chemistry; surface chemistry; adsorption; ellipsometry; QCM-D; DPI; protein adsorption; polypeptides; biomaterials; biosurfaces; amelogenin; solid liquid interface; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The cellular response to a biomaterial, such as a dental implant, is mainly governed by the surface properties, and can thus be altered by the introduction of a surface coating. In this thesis the buildup of a biomacromolecule-based coating formed by layerby-layer (LbL) deposition of the charged polypeptides poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) has been studied.

  7. 10. Reaching Kinetic Selectivities : In Pursuing Novel Ternary Oxide Coatings, and Beyond

    Författare :Sebastian Öhman; Mats Boman; Tobias Törndahl; Maarit Karppinen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CVD; coatings; kinetics; crystallization; nucleation; diffusionless; Al2TiO5; oxides; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Kinetically driven synthesis pathways have the potential to allow new ways to develop materials and phases with much-improved properties. This particularly concerns metastable and multicomponent phases that require a selective kinetic targeting during the synthesis to circumvent the formation of thermodynamically stable products.
