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

    Author : Amanda Persdotter; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Litao Yin; Jinshan Pan; Christopher Leygraf; Ying Jin; Herman Terryn; KTH; []
    Keywords : 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;

    Abstract : 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.

  6. 4. Beyond Breakaway Corrosion: Investigating the Secondary corrosion protection of Iron-based alloys

    Author : Amanda Persdotter; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; High temperature corrosion; Breakaway oxidation; Fe-based alloys; Iron oxide; Secondary corrosion protection;

    Abstract : High temperature corrosion of metallic materials remains a major challenge for many in-dustrial applications. The challenges of high temperature corrosion are often addressed by using highly alloyed materials such as stainless steels or FeCrAl alloys. READ MORE

  7. 5. Corrosion Fatigue of Stainless Steels

    Author : Jan Linder; KTH; []
    Keywords : Stainless steel; corrosion fatigue; crack propagation; spot weld;

    Abstract : The aim of this work was to investigate the effect ofchloride-containing environments on corrosion fatigueproperties for different stainless steels grades. The steelsinvestigated ranged from the standard 304 grade to thesuperaustenitic 654SMO and the superduplex SAF2507. READ MORE
