  2. 6. On tool steel, surface preparation, contact geometry and wear in sheet metal forming

    Author : Fredrik W. Lindvall; Jens Bergström; Staffan Jacobson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; Galling; sheet metal; deep drawing; Tool steel; surface preparation; Friction; Materialteknik; Materials Engineering;

    Abstract : In sheet metal forming operations the life length of the production equipment islargely dependent on the wear of the tools that are in direct contact with the sheet.One form of adhesive wear where some sheet material gets transferred to the tool, alsoknown as galling, is the most common cause of tool failure.

  4. 7. Gear tribology : friction and surface topography

    Author : Li Xiao; Bengt-Göran Rosén; Liam Blunt; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; Surface topography; Toughness; Lay; Gears; Power transmission; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The quest for energy efficiency leads to the development of highly efficient power transmissions for vehicles. Gears are some of the most rugged and durable torque transmitters among machine elements. Friction between sliding surfaces at gear teeth is one major source of power loss. READ MORE

  5. 8. Surface Modifications and Applications of Aqueous Silica Sols

    Author : Peter Greenwood; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applications; Surface modification; aqueous; silica sol; silane; colloidal silica; titania;

    Abstract : Methods of modifying the surface of the particles of colloidal silica were developed and the effects of surface modification on the properties of colloidal silica were studied.Gamma-glycidoxypropyltrimethoxysilane (GPTMS) readily reacts with water to yield a hydrolysed silane that reacts readily with the silica surface.

  6. 9. Biomimetic surfaces : Preparation, characterization and application

    Author : Annika Borgh; Bo Liedberg; Fredrik Höök; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Self-assembled monolayers; biomimetic surfaces; phosphates; antifreeze; surface spectroscopy; Molecular physics; Molekylfysik;

    Abstract : I denna avhandling beskrivs tillverkning, karaktärisering och tillämpning av ett antal biomimetiska ytor. Biomimetik är att härma naturen och grundtanken är att titta på hur naturen löst liknande problemställningar. READ MORE

  7. 10. Fiber-Supported Hydrogels with Controlled surface Properties

    Author : Jan Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellulose; fiber; ozone; polypropylene; graft polymerization; hydrogel; surface;

    Abstract : Hydrogels are emerging materials that have the ability to hold a substantial amount of water. However, the low mechanical performance of hydrogels is often a limitation for extending the field of applications. READ MORE
