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.

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 ...
