  3. 3. Tribology of stamping : the influence of designed steel sheet surface topography on friction

    Detta är en avhandling från Göteborg : Chalmers tekniska högskola

    Författare :Daniel Wiklund; Högskolan i Halmstad.; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik; steel sheet; tribology; surface topography; Ytbehandlingsteknik; Surface engineering;

    Sammanfattning : Tribology is the science of friction, wear, and lubrication; the interaction of surfaces in relative motion. The tribological conditions in sheet metal forming influences the flow of material in forming operations, the strain distributions of sheet material, extent of wear, and thereby the quality of products.
