  3. 7. Formation of non-metallic inclusions and the possibility of their removal during ingot casting

    Författare :Lars Ragnarsson; Sichen Du; Carlo Mapelli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ingot casting; tool steel; inclusion; runner; refractory; erosion; casting powder; cold model; argon shroud; reoxidation; oxygen measurement; CFD; PIV; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : The present study was carried out to investigate the formation and evolution of non-metallic inclusions during ingot casting. Emphasize have been on understanding the types of inclusions formed and developed through the casting process and on the development of already existing inclusions carried over from the ladle during casting.

  7. 10. The synergistic role of hierarchical macro- and mesoporous implant surface and microscopic view of enhanced osseointegration

    Författare :Guang Han; Zhijian Shen; Anders Palmqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Porosity; cell adhesion; cell proliferation; surface topography; implant; bone-implant interface; argon ion beam polishing; osteogenesis; osseointegration; Materials Chemistry; materialkemi;

    Sammanfattning : The trend for designing of a titanium implant explored using different chemical compositions and crystallinity materials until people realized that the implant surface character was another important factor affecting the rate and extent of osseointegartion. Titanium received a macroporous titania surface layer by anodization, which contains open pores with average pore diameter around 5μm. LÄS MER
