  1. 1. Environmental and health aspects of corrosion– importance of chemical speciation

    Detta är en avhandling från Stockholm, Sweden : KTH

    Författare :Yolanda Hedberg; KTH.; [2010]
    Nyckelord :;

    Sammanfattning : During the last decades, the interest in corrosion of metals and alloys from an environmental and health perspective has increased rapidly as a consequence of stricter environmental and human exposure legislations, their extensive use as implant materials and an increasing understanding related to occupational and/or daily exposure to airborne particles. Corrosion-induced metal release, however, needs to be understood in detail and to include knowledge related to chemical speciation, i. LÄS MER

  2. 2. Stainless Steel in Biological Environments – Relation between Material Characteristics, Surface Chemistry and Toxicity

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Yolanda Hedberg; KTH.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Triggered by the regulatory need of the industry to demonstrate safe use of their alloy products from an environmental and health perspective, and by the significant lack of metal release data and its correlation to material and surface characteristics for iron- and chromium-based alloys, a highly interdisciplinary in-depth research effort was undertaken to assess the relation between material/surface characteristics and toxicity with main emphasis on stainless steel alloys. This thesis focuses predominantly on studies made on AISI 316L both as massive sheet and as powder particles, but includes also results for other stainless steel grades and reference metals and metal oxides.
