2. 1. Nanoscale studies of the atmospheric corrosion of copper protected by ultrathin organic films

   Author : Weijie Zhao; C. Magnus Johnson; Christopher Leygraf; Guido Grundmeier; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric corrosion; copper; corrosion inhibition; Langmuir-Blodgett LB deposition; self-assembly deposition; nano-FTIR; octadecylphosphonic acid ODPA .; Kemi; Chemistry;

   Abstract : Copper (Cu) has been utilised by humans for millenniums and has become an indispensable metal in modern industry and in our infrastructure. However, corrosion, as a natural process for metallic materials, takes place on copper surfaces in most environments. READ MORE

4. 2. 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.

   Abstract :    With the advancement and accessibility of local probing techniques that can operate at the submicron scale it has become possible to analyse the local corrosion properties of industrially important metallic materials and relate these properties to microstructure characteristics of the same materials. In this doctoral study the focus has been on copper-zinc samples, both as industrial brass alloys and as micro-patterned copper-zinc samples. READ MORE

7. 5. 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
