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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mattias Berger; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; TiB2; Tribology; Magnetron Sputtering; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : 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. READ MORE

  3. 3. Tribological nature of squealing disc brakes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis
