  2. 1. Design of carbide-based nanocomposite coatings

    Author : Erik Lewin; Ulf Jansson; Jörg Patscheider; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chemistry; thin film; dc magnetron sputtering; carbide; nanocomposite; PVD; solid solution; Chemistry; Kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; Oorganisk kemi;

    Abstract : In this thesis research on synthesis, microstructure and properties of carbide-based coatings is reported. These coatings are electrically conducting, and can be tailored for high hardness, low friction and wear, along with load-adaptive behaviour. Tailoring these properties is achieved by controlling the relative phase content of the material. READ MORE

  4. 2. Development and performance evaluation of accident-tolerant coated fuel claddings for light water reactors

    Author : Andrea Fazi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVD; oxidation; accident tolerant fuel; autoclave; cold spray; nitride coatings; Cr coating;

    Abstract : The development of accident tolerant fuel has the aim of providing nuclear fuels able to endure severe accident conditions. Research in this field has also sparked a wave of material renewal in the nuclear industry that had been delayed for the last few decades. READ MORE

  5. 3. Synthesis and Characterization of Amorphous Carbide-based Thin Films

    Author : Matilda Folkenant; Ulf Jansson; Erik Lewin; Paul Mayrhofer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous; coating; thin film; nanocomposite; sputter deposition; PVD; XPS; SEM; TEM; electrical properties; mechanical properties;

    Abstract : In this thesis, research on synthesis, structure and characterization of amorphous carbide-based thin films is presented. Crystalline and nanocomposite carbide films can exhibit properties such as high electrical conductivity, high hardness and low friction and wear. READ MORE

  6. 4. Synthesis and Characterization of Ternary Carbide Thin Films

    Author : Ola Wilhelmsson; Ulf Jansson; Michael Stueber; Uppsala universitet; []
    Keywords : Chemistry; Thin film; dc magnetron sputtering; tribology; carbide; PVD; MAX-phase; DFT; solid solution; Kemi;

    Abstract : This thesis reports on synthesis, microstructure and properties of binary and ternary carbide thin films deposited by dc magnetron sputtering. These materials are interesting since they exhibit a wide range of useful properties, such as high hardness, resistance to wear and oxidation, and high electrical conductivity. READ MORE

  7. 5. Self Lubrication on the Atomic Scale : Design, Synthesis and Evaluation of Coatings

    Author : Mattias Lindquist; Sture Hogmark; Urban Wiklund; Ian Hutchings; Uppsala universitet; []
    Keywords : Materials science; Tribology; low friction; PVD; sputtering; nanocomposite; Materialvetenskap;

    Abstract : In this thesis a new design concept of tribologically active coatings aimed for low friction applications, have been explored. Materials modeled by ab initio DFT calculations were realized through deposition of carbide and nanocomposite coatings by DC-magnetron sputtering. READ MORE
