  2. 1. Engineering Ceramics for Tribological Systems. Manufacture, Properties and Testing

    Author : Lars Kahlman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal wear; ceramic composite; face seal; engineering ceramic; erosion; hybrid bearing; thermal spalling; lubrication; tribology; abrasive waterjet; abrasive wear;

    Abstract : A broad range of commercial and experimental grades of ceramics and ceramic composites was tested in various model tests and simplified component tests. The tests were done to establish important microstructural features, friction and wear mechanisms. READ MORE

  4. 2. Thermal shock and thermal fatigue in ceramic materials

    Author : Tomas Andersson; KTH; []
    Keywords : ;

    Abstract : This thesis concerns thermal stress fracture in ceramicmaterials. The work describes a new technique for determiningthe thermal shock resistance of brittle materials as well asexperimental results and thermal stress simulations. READ MORE

  5. 3. Design of Thermal Barrier Coatings : A modelling approach

    Author : Mohit Kumar Gupta; Per Nylén; Nicolaie Markocsan; Christer Persson; Lech Pawlowski; Högskolan Väst; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Robert Eriksson; Sten Johansson; Michael Schütze; Linköpings universitet; []
    Keywords : ;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
