Emergence of micro-galvanic corrosion in plastically deformed austenitic stainless steels

Materials & Design, 2021
Localized plastic deformation has been observed to render nuclear reactor components more susceptible to stress corrosion cracking (SCC). However, it is not fully clear how localized strain impacts corrosion (oxidation) behavior.

Towards understanding micro-galvanic activities in localised corrosion of AA2099 aluminium alloy

Electrochimica Acta, 2021
Abstract The micro-galvanic interactions between Cu-Fe-Mn-Li-containing aluminides and the alloy matrix of aluminium alloy AA2099 during chloride-induced corrosion were investigated in-situ with real-time monitoring of the local contact potential difference (VCPD) using the scanning Kelvin probe force microscopy (SKPFM) at controlled relative ...

Correlation of micro-galvanic corrosion behavior with corrosion rate in the initial corrosion process of dual phase steel

Journal of Materials Research and Technology, 2021
The initial corrosion process of dual phase (DP) steel produced by the continuous annealing process (CAP) in NaCl solution was systematically studied in this paper. The microstructure, nobility of the phases, and micro-galvanic corrosion behavior were characterized by scanning electron microscope (SEM), electron backscattered diffraction (EBSD ...

Influence of Cerium on the Formation of Micro-Galvanic Corrosion Elements of AZ91 [PDF]

Materials Science Forum, 2011
Investigations of AZ91D revealed a strong influence of mainly the following microstructural parameters on corrosion: porosity, the eutectic, the Al-content of the Mg-phase as well as the volume fraction and distribution of gamma-Al12Mg17. Further an improved corrosion resistance was observed by the addition of rare earth elements.
