  1. 1. Development and tribological characterisation of magnetron sputtered TiB2 and Cr/CrN coatings

    Författare :Mattias Berger; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; TiB2; Tribology; Magnetron Sputtering; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : The aim of this thesis was to develop wear resistant physical vapour deposited coatings of TiB2 as well as multilayers of Cr/CrN. The correlation between deposition parameters and fundamental coating properties such as microstructure, composition, residual stress and hardness has been investigated. LÄS MER

  5. 4. Magnetron Sputter Epitaxy of CrB2/TiB2 Diboride Superlattice Thin Films

    Författare :Samira Dorri; Jens Birch; Vassilios Kapaklis; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Artificial superlattices with their exceptional properties have been popular in a broad range of applications such as electronic, magnetic, optical, and hard coating. Another potential application for single crystal artificial superlattices is highly efficient interference neutron optics, owing to an ultimate interface width of just ±½ atomic layer. LÄS MER

  7. 5. Spark plasma sintering and deformation behaviour of Titanium and Titanium/TiB2Spark plasma sintering and deformation behaviour of Titanium and Titanium/TiB2 composites

    Författare :Mirva Eriksson; Zhijian Shen; Guocai Chai; Stockholms universitet; []
    Nyckelord :materialvetenskap; Materials Science;

    Sammanfattning : Titanium has been used as a model substance to study how it behaves in a SPS apparatus when heating rate and/or pressure were varied during the sintering and deformation process. The sintering and deformation of Ti in SPS were compared with that occurring in the conventional hot pressing (HP) in order to reveal if there are any positive effects added by the use of SPS. LÄS MER
