    Sammanfattning : Physically vapour deposited multilayered coatings were the target of this thesis.Several different wear resistant nitride coatings (TiN/CrN, TiN/MoN, TiN/NbN andTiN/TaN) have been evaluated. LÄS MER

  3. 12. Craniofacial bone tissue engineering with biomimetic constructs

    Författare :Gregory Tour; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :bone regeneration;

    Sammanfattning : The repair of bone defects and nonunions remains a significant clinical problem in orthopedic and maxillofacial reconstructive surgery. Tissue engineering offers a potential approach to overcome existing limitations related to auto- and allograft tissues. LÄS MER

  4. 13. Thermodynamic modelling of aqueous solutions and applications in some functional materials synthesis

    Författare :Mingsheng Wang; KTH; []
    Nyckelord :;

    Sammanfattning : Modern advances in science and technology require thedevelopment of functional materials with improved performance.Such engineered materials often have a very complex compositionand specific microstructures. These factors impose a seriouschallenge for the synthesis and processing of advancedfunctional materials. LÄS MER

  5. 14. Chemical vapor deposition of hard coatings : Development of W(C,N) coatings for cemented carbide and TiN deposition on a CoCrFeNi substrate

    Författare :Katalin Böőr; Mats Boman; Markku Leskelä; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : There is a constant need for cutting tool material development to be able to machine new materials and improve the metal cutting efficiency. Inserts of indexable cutting tools usually consist of WC-Co cemented carbide (cc) with μm thick layers of ceramic coatings. LÄS MER

  7. 15. Design of Thermal Barrier Coatings : A modelling approach

    Författare :Mohit Kumar Gupta; Per Nylén; Nicolaie Markocsan; Christer Persson; Lech Pawlowski; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal barrier coatings; Microstructure; Thermal conductivity; Young’s modulus; Interface roughness; Thermally grown oxide; Lifetime; Finite element modelling; Design; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Atmospheric plasma sprayed (APS) thermal barrier coatings (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. TBC is a duplex material system consisting of an insulating ceramic topcoat layer and an intermetallic bondcoat layer. LÄS MER
