Susceptibility of rare-earth-magnesium alloys to micro-galvanic corrosion

Corrosion Science, 2010
Abstract Four commercially produced rare-earth-magnesium alloys, as-cast ZE41, sand-cast WE43-T6, and wrought WE43-T6 and WE54-T6, were studied by scanning Kelvin probe force microscopy (SKPFM) in order to evaluate the role of their micro-constituent phases on potential galvanic interactions.

Insight into the localized strain effect on micro-galvanic corrosion behavior in AA7075-T6 aluminum alloy

Corrosion Science, 2021
Abstract Micro-galvanic corrosion behaviors between two primary intermetallic particles (Mg2Si, α(Al-Fe-Cu)) and the Al matrix were investigated under elastic and plastic deformations in AA7075-T6. Strain localization was mainly concentrated within Mg2Si and at the interface of α(Al-Fe-Cu)/Al matrix under deformations.

Micro-galvanic corrosion of Cu/Ru couple in potassium periodate (KIO 4 ) solution

Corrosion Science, 2018
Abstract This paper focuses on the study of micro-galvanic corrosion of the Cu/Ru couple in KIO4 solution. Practical nobility across the Cu/Ru interface was evaluated by Volta potential mapping, and the morphological changes were monitored by in-situ atomic force microscopy measurements during exposure in a KIO4 solution.
