  1. 1. Property measurements towards understanding process phenomena

    Author : Riad Abdul Abas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : The main objective of this industrially important work was to gain an increasing understanding of the properties of materials such as CMSX-4 nickel base super alloy, mould powder used in continuous casting of steel and coke used in blast furnace, with special reference to the thermal diffusivities. The measurements were carried out in a wide temperature range, solid, liquid, glassy and crystalline states. READ MORE

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

    Author : Mattias Berger; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; TiB2; Tribology; Magnetron Sputtering; Materialvetenskap; Materials science; 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

    Author : Filip Bergman; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : In the stiff competition between car manufacturers, silent and vibration free brakes hasbecome increasingly important. The aim of the present work is to increase the knowledge of the fundamental friction mechanisms operating in brake systems and to study the parameters influencing disc brake squeal generation.
