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

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

    Abstract : 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. READ MORE

  5. 8. Atmospheric corrosion and runoff processes on copper and zinc as roofing materials

    Author : Wenle He; KTH; []
    Keywords : atmospheric corrosion; corrosion rate; runoff rate; copper; zinc; field study; laboratory study; roof; first flush; rain quantity; rain intensity; rain pH; dry and wet deposition; corrosion and runoff process;

    Abstract : An extensive investigation with parallel field andlaboratory exposures has been conducted to elucidateatmospheric corrosion and metal runoff processes on copper andzinc used for roofing applications. Detailed studies have beenperformed to disclose the effect of various parameters on therunoff rate including: surface inclination and orientation,natural patination (age), patina composition, rain duration andvolume, rain pH, and length of dry periods inbetween rainevents.

  6. 9. Atmospheric corrosion of copper and copper-based alloys in architecture : from native surface oxides to fully developed patinas

    Author : Tingru Chang; Inger Odnevall Wallinder; Tomas Prošek; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Copper and copper-based alloys are commonly used in both ancient and modern architecture. This requires an in-depth fundamental and applied understanding on their atmospheric corrosion behavior at different climatic, environmental and pollutant levels and how these parameters influence e.g. READ MORE

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

    Author : Xian Zhang; Inger Odnevall Wallinder; Christofer Leygraf; Manuel Morcillo; KTH; []
    Keywords : 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;

    Abstract : 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.
