  3. 2. FEM Modelling of Micro-galvanic Corrosion in Al Alloys Induced by Intermetallic Particles : Exploration of Chemical and Geometrical Effects

    Författare :Litao Yin; Jinshan Pan; Christopher Leygraf; Ying Jin; Herman Terryn; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Method FEM ; Modelling; Micro-galvanic corrosion; Al alloy; corrosion product deposition; chemical factors; steric hindrance effect; Kemi; Chemistry;

    Sammanfattning : Localized corrosion, such as pitting, crevice corrosion or galvanic corrosion, is a long-standing phenomenon that can greatly limit the life of metallic materials. For decades experimental methods have been used to try to understand the underlying physical, chemical and electrochemical processes that control localized corrosion in order to find effective protection methods against its propagation.

  4. 3. Development of ATR-FTIR Kretschmann Spectroscopy for In situ Studies of Metal / Polymer Interfaces : and its Intergration with EIS for Exposure to Corrosive Conditions

    Författare :Maria Öhman; Christofer Leygraf; Herman Terryn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The environmental stability of a metal / polymer interface is essential for the durability and mechanical stability of constructions in several important areas such as the automotive, offshore, building and aerospace industries. The protective capability of a polymer film is strongly connected to its barrier properties, but the transport of water and corrosive constituents through the polymer and the subsequent processes at the metal surface are complicated to analyse in detail.
