  1. 11. Corrosion resistant alumina-forming alloys for lead-cooled reactors

    Författare :Jesper Ejenstam; Inger Odnevall Wallinder; Il Soon Hwang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

    Sammanfattning : Generation IV nuclear power technologies provide attractive solutions to the common issues related to conventional nuclear power plants currently in operation worldwide. Through a significant reduction of the long-term radiotoxicity of nuclear waste, a more efficient use of nuclear fuel resources, and implementation of inherent safety features, Generation IV will make nuclear power sustainable and thus increase the public acceptance of nuclear power.

  2. 12. High temperature corrosion in biomass-fired energy applications : Alloying effects and test environment comparisons

    Författare :Ragna Elger; Rachel Pettersson; Inger Odnevall Wallinder; Rikard Norling; Gordon Tatlock; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; High temperature corrosion; biomass; waste; superheater corrosion; austenitic steel; biomass gasification; alumina-forming austenitic stainless steel; thermodynamic modelling; kinetic modelling; Kemi; Chemistry;

    Sammanfattning : To reduce the greenhouse effect, the use of renewable fuel has to be increased. As renewable fuel has different characteristics compared to fossil fuel regarding content of trace metals, alkali, chlorine and sulphur, the corrosion characteristics in high temperature energy processes have to be evaluated.

  3. 13. Environmental and health aspects of corrosion– importance of chemical speciation

    Författare :Yolanda Hedberg; Inger Odnevall Wallinder; Anna Karin Borg Karlsson; Susanna Wold; KTH; []
    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

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

    Författare :Yolanda Hedberg; Inger Odnevall Wallinder; Sasha Omanovich; KTH; []
    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.

  5. 15. Bioaccessibility of Stainless Steels : Importance of Bulk and Surface Features

    Författare :Gunilla Herting; Inger Odnevall Wallinder; Stuart Lyon; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stainless steel; iron; chromium; nickel; corrosion; metal release; artificial rain; synthetic body fluids; acetic acid; surface oxide; surface finish; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : With increasing environmental awareness, the desire to protect human beings and the environment from adverse effects induced by dispersed metals has become an issue of great concern and interest. New policies, such as REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) within the European Community, have been implemented to reduce hazards posed by the use of chemicals on producers and downstream users.
