  3. 2. Combustion Valve Wear : A Tribological Study of Combustion Valve Sealing Interfaces

    Författare :Peter Forsberg; Staffan Jacobson; Rob Dwyer-Joyce; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion valves; wear; tribofilm; test rig; combustion residue; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : The exhaust valve system of combustion engines experiences a very complex contact situation of frequent impact involving micro sliding, high and varying temperatures, complex exhaust gas chemistry and possible particulates, etc. In addition, the tribological situation in the exhaust valve system is expected to become even worse due to strict future emission regulations, which will require enhanced combustion and cleaner fuels.

  4. 3. Assembly of the Caledonian Orogenic Wedge, Jämtland, Sweden

    Författare :Hagen Bender; Uwe Ring; Bjarne SG Almqvist; Rob Strachan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; collisional orogeny; Scandinavian Caledonides; Seve Nappe Complex; Köli Nappe Complex; in-sequence thrusting; out-of-sequence thrusting; imbrication; nappe stacking; orogenic wedge assembly; Rb–Sr geochronology; rock magnetism; anisotropy of magnetic susceptibility; Geology; geologi;

    Sammanfattning : Collisional orogeny creates the largest mountain belts on Earth. The Caledonides of Scandinavia are a deeply eroded, ancient mountain belt, which today exposes a deep section through the former orogenic interior. LÄS MER

  5. 4. Ionic lubricants : Molecular features and surface protection mechanisms

    Författare :Bulat Munavirov; Sergei Glavatskih; Istvan Furo; Rob Dwyer-Joyce; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ionic liquid; lubrication technology; tribology; boundary lubrication; tribofilm; friction; wear; physico-chemical interaction; diffusion NMR; jonisk vätska; smörjteknik; tribologi; gränsskiktssmörjning; tribofilm; friktion; slitage; fysikalisk-kemisk interaktion; NMR diffusometri; Machine Design; Maskinkonstruktion;

    Sammanfattning : In this thesis ionic liquids (ILs) are investigated as prospective candidates for lubrication. Three custom synthesized phosphonium orthoborate type ILs were extensively studied from the prospective of molecular structuring both in bulk and at the interface and from the prospective of their lubricating performance as neat lubricants and as additives in oils.

  7. 5. Characterisation of residues : Release of contaminants from slags and ashes

    Författare :Ann-Marie Fällman; Rob N.J. Comans; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Residues from industrial processes as well as from energy production utilities have in many cases properties similar to geological materials. They can be used as filling and construction materials if the net environmental impact and the technical properties are acceptable. LÄS MER
