1. 11. Design of carbide-based nanocomposite coatings

   Författare :Erik Lewin; Ulf Jansson; Jörg Patscheider; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 15. Carbide and MAX-Phase Engineering by Thin Film Synthesis

   Författare :Jens-Petter Palmquist; Ulf Jansson; M. Jochen Schneider; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Thin films; microstructure; epitaxy; carbide; WC; MAX-phase; Ti3SiC2; DC magnetron sputtering; PVD; Reciprocal Space Mapping; RSM; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : This thesis reports on the development of low-temperature processes for transition metal carbide and MAX-phase thin film growth. Magnetron sputtering and evaporation, far from thermodynamical equilibrium, have been utilised to engineer the properties of the films by physical and chemical control. LÄS MER
