  2. 16. Low-friction and wear-resistant carbon nitride coatings for bearing components grown by magnetron sputtering

    Author : Konstantinos Bakoglidis; Grzegorz Greczynski; Lars Hultman; Susann Schmidt; Witold Gulbinski; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon nitride; magnetron sputtering; physical vapor deposition; coatings; bearings; rolling contact fatigue; adhesion; friction; wear; transmission electron microscopy; scanning electron microscopy; x-ray photoelectron spectroscopy; coatings tribology; nanotribology;

    Abstract : 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. READ MORE

  4. 17. Fatigue limit, inclusion and finite lives - a statistical point of view

    Author : Sara Lorén; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; censoring; likelihood; profile predictive likelihood; staircase test; extreme value; likelihood;

    Abstract : An important design property of steel is the fatigue limit, i.e. the load level where a specimen has infinite life. For the material it can also be defined an endurance limit, which is the stress level at which the specimen has a certain life. READ MORE

  5. 18. Material characterization for magnetically confined fusion : Surface analysis and method development

    Author : Petter Ström; Marek Rubel; Per Petersson; Thierry Loarer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The dream of abundant clean energy has brought scientists and laypeople alike to ponder the possibilities of nuclear fusion since it was established as the energy source of the stars in 1939. Starting from the mid-twentieth century, significant effort has been put into overcoming the technological challenges related to the construction of a power plant, but initial optimism has faded somewhat due to a notable absence of practical outcomes.

  6. 19. Investigation of Interactions between Liquid Iron Containing Oxygen and Aluminosilicate Refractories

    Author : Era Kapilasharmi; KTH; []
    Keywords : ;

    Abstract : The present work was initiated to investigate runnerrefractory corrosion by molten steel. The aim was to understandthe mechanism of inclusion formation during ingot casting. Thework is also of interest to other unit processes in steelmaking, where refractory corrosion and erosion are seriousproblems. READ MORE

  7. 20. Towards Abatement of Selected Emissions from Metals Manufacturing

    Author : Diana Orrling; Seshadri Seetharaman; S. Subramanian; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; Materials science; Teknisk materialvetenskap;

    Abstract : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. READ MORE
