  1. 16. First Principle Studies of Functional Materials : Spintronics, Hydrogen Storage and Cutting Tools

    Författare :Fredrik Silvearv; Ahuja Rajeev; Ali Zaoui; Uppsala universitet; []
    Nyckelord :spintronics; hydrogen storage; coating materials; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : The properties of functional materials have been studied with density functional theory. The first type of materials that have been investigated is the so called diluted magnetic semiconductors. It is a new class of materials that could offer enhanced functionality by making use of spin in addition to the charge of the electron. LÄS MER

    Sammanfattning : The scope of this thesis is the investigation of magnetron sputtered carbon nitride coatings suitable for roller bearing components. The research field of tribology of bearings focuses on minimizing friction between components by improving the lubricants. LÄS MER

  4. 18. Low Friction and Wear Resistant Carbon Nitride Thin Films for Rolling Components Grown by Magnetron Sputtering

    Författare :Konstantinos D. Bakoglidis; Lars Hultman; Grzegorz Greczynski; Susann Schmidt; Esteban Broitman; Tomas Kubart; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The scope of this licentiate thesis is the investigation of carbon based thin films suitable for rolling components, especially roller bearings. Carbon and carbon nitride are materials with advantageous tribological properties and high resiliency. LÄS MER

  5. 19. Wear Mechanisms in Cutting Tools for Machining Applications : Interfacial Phenomena, Characterization, and Relation to Performance

    Författare :Rebecka Lindvall; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Metal cutting technology plays an important role in the automotive and aeronautic sectors, both of whichare important for the Swedish economy. Both make use of traditional grey cast iron and difficult-to-machine materials like titanium alloys and compacted graphite iron. LÄS MER

  7. 20. Towards more sustainable approaches for protecting surfaces against wear
