  4. 4. Atmospheric corrosion of zinc-aluminum and copper-based alloys in chloride-rich environments Microstructure, corrosion initiation, patina evolution and metal release

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

    Författare :Xian Zhang; KTH.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmospheric corrosion; chloride deposition; Zn-Al alloy coatings on steel microstructure; Cu sheet and Cu alloys; microstructure; corrosion initiation; corrosion product evolution; metal release; SEM; IRAS; CRM.; Kemi; Chemistry;

    Sammanfattning : Fundamental understanding of atmospheric corrosion mechanisms requires an in-depth understanding on the dynamic interaction between corrosive constituents and metal/alloy surfaces. This doctoral study comprises field and laboratory investigations that assess atmospheric corrosion and metal release processes for two different groups of alloys exposed in chloride-rich environments.
