  2. 11. Structure and properties of Si-C-N and B-C-N thin films prepared by magnetron sputtering

    Author : Torun Berlind; Linköpings universitet; []
    Keywords : ;

    Abstract : Carbon nitride-based materials, grown by magnetron sputtering have been studied concerning microstructure and mechanical properties. Carbon nitride was alloyed with Si or B, and grown as a constituent in a layered structure. READ MORE

  4. 12. High Temperature Tribology of Aluminium : Effect of Lubrication and Surface Engineering on Friction and Material Transfer

    Author : Justine Decrozant-Triquenaux; Jens Hardell; Manel Rodriguez Ripoll; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : Lightweight design for automotive applications has been pursued for several decades and continues to increase. The main driving forces are new and increasingly stringent emission regulations as well as the increasing popularity of electric, or hybrid, vehicles where the increased weight of the batteries need to be compensated by light weight structures.

  5. 13. Tribological behaviour of polymers in lubricated contacts

    Author : Arash Golchin; Klaus Friedrich; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : An important issue in hydropower and other industries is the increasing demand for introduction of environment friendly solutions. Mineral oil based lubricants have long been used in various sliding bearings in hydropower stations. READ MORE

  6. 14. HiPIMS-based Novel Deposition Processes for Thin Films

    Author : Asim Aijaz; Ulf Helmersson; Kostas Sarakinos; Linköpings universitet; []
    Keywords : ;

    Abstract : In this research, high power impulse magnetron sputtering (HiPIMS) based new deposition processes are introduced to address; the issue of low degree of ionization of C in magnetron sputtering discharges, and the difficulty encountered in thin film deposition on complex-shaped surfaces. The issue of low degree of C ionization is addressed by introducing a new strategy which is based on promoting the electron impact ionization ofC by increasing the electron temperature in the plasma discharge using Ne, instead of conventionally used Ar.

  7. 15. Investigations for enhanced tribological performance of a hydraulic motor

    Author : Daniel Nilsson; Friedrich Franek; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : A radial piston hydraulic motor has several components that encounter sliding orrolling motion under lubricated conditions. When a hydrostatic, hydrodynamic orelastohydrodynamic oil film separates the interacting surfaces, the wear and frictionare low provided of course the hydraulic fluid is free from the presence ofcontaminants.
