  1. 16. On Tool Failure in Die Casting

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anders Persson; Uppsala universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Die casting is a very cost-efficient method of forming thin-walled and complex near net-shaped products with close geometric tolerances and good surface finish. A permanent die tool is used to make large quantities of identical products. The performance and tool life are limited by several mechanisms, e.g. READ MORE

  2. 17. Minuscular sculpturing

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Greger Thornell; Uppsala universitet.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Most of the processes employed in microstructure technology have been adopted from the fabrication scheme of integrated circuits (IC). Although being extremely reliable and cost efficient, they suffer from poor material and geometrical flexibility. READ MORE

  3. 18. Mechanics and tribology of micro- and nanolayered PVD coatings

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Urban Wiklund; Uppsala universitet.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Thin coatings produced by physical vapour deposition (PVD) are increasingly applied tomechanical components such as metal cutting tools, forming tools and machine elements.Improved micro- and nanolayered PVD coatings have been studied with respect tomechanical and tribological properties.

  4. 19. Wear resistant low friction coatings for machine elements

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Olle Wänstrand; Uppsala universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : By the introduction of machine elements made of light metals, e.g. Al or Mg alloys, which are coated with a material providing high wear resistance and low friction coefficient, both economical and environmental benefits can be gained. A high resistance against wear results in increased lifetime and lower costs for spare parts and maintenance. READ MORE

  5. 20. Interfacial Phenomena in Two-Phase systems: Emulsions and slag Foaming

    University dissertation from Stockholm : Materialvetenskap

    Author : Abha Kapilashrami; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; film formation; o w emulsion; substrate effect; slag forming; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : In the present work studies were performed to provide understanding for further model development of the two-phase phenomena, film formation from o/w emulsions and slag foaming.The drying of o/w emulsions of different oil viscosities on hydrophobic and hydrophilic substrates was studied.
