  1. 1. Polishability of tool steels : Characterisation of high gloss polished tool steels

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Sabina Rebeggiani; Högskolan i Halmstad.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science Surface engineering; TEKNIKVETENSKAP Teknisk materialvetenskap Ytbehandlingsteknik; tool steels; surface characterisation; polishability; 3D parameters; high gloss polishing; Tool steels;

    Abstract : The manufacturing of plastic components, like a majority of other mass produced discrete parts, require well designed dies and moulds. Complex geometries and increasing demands on final surface appearance, which is strongly connected to the quality impression, are pushing for high demands on mould-makers and polishers as well as steel producers.
