  1. 11. Application of copper corrosion inhibitors in mineral oil : Surface analytical studies and corrosion mitigation evaluations

    Författare :Martina Levin; Christofer Leygraf; Per Redelius; Roy Johnsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This doctoral thesis explores the copper corrosion inhibiting properties of a number of nitrogen containing hetero-organic compounds in refined mineral oil. Traditional organic corrosion inhibitors, as well as novel and bioorganic compounds have been studied. LÄS MER

  3. 12. Beyond Breakaway Corrosion: Secondary Corrosion Protection of Iron-based Alloys

    Författare :Amanda Persdotter; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Breakaway oxidation; High temperature corrosion; Fe-based alloys;

    Sammanfattning : Metallic materials intended for high temperature applications must resist both mechanical and environmental degradation. The ability to withstand corrosion is an important aspect of high temperature materials and is of major concern in, for example, heat and power production. LÄS MER

  4. 13. High temperature corrosion of low-alloyed and stainless steels: mechanistic study of chlorine-induced corrosion

    Författare :Mercedes Andrea Olivas Ogaz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steels; low-alloyed steels; pre-oxidation; High temperature corrosion; chlorine-induced corrosion;

    Sammanfattning : The global demand on power generation is constantly increasing and so far, also its environmental impact. The environmental impact could primarily be directed to the power generation being based on fossil fuels, giving a net increase of CO2 to the atmosphere when combusted. LÄS MER

  5. 14. Use of localised techniques to elucidate the influence of process variables on the corrosion of stainless steels

    Författare :Nuria Fuertes; Rachel Pettersson; Inger Odnevall; Stuart Lyon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; corrosion; passive film; thermal oxides; Volta potential; pickling; deformation; cold rolling; AM; SKPFM; SVET; Kemi; Chemistry;

    Sammanfattning : Several factors during steel manufacture and fabrication can alter the passivity and corrosion behaviour of stainless steels. These include alloying, deformation, welding and heat treatments. LÄS MER

  7. 15. Corrosion of painted galvanized steel pretreated with Zr-based thin films

    Författare :Konrad Tarka; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HDG; cyclic corrosion test; SEM; EDS; XRD; Atmospheric corrosion;

    Sammanfattning : For decades, phosphating has been considered state of the art for pretreating car bodies in order to promote corrosion resistance and paint adhesion. Although it offers excellent corrosion protection, the phosphating process has drawbacks. LÄS MER
