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.

Abstract A finite element method model has been elaborated aiming at a deeper insight into the influence of microstructure on micro-galvanic corrosion of Al alloys. The model considers a dynamic corroding surface and takes into account kinetic data from local electrochemical reactions, transport of O 2 and ionic species (e.g., Al 3+ , H + , Cl ...

Journal of Magnesium and Alloys, 2023 A model specimen with a single boundary of the α/β phase simulating Mg-Al alloys was successfully fabricated by spark plasma sintering. A small electrode area of α phase or β phase was prepared using the model specimen, and the OCPs (open-circuit potentials) of each phase and a small electrode area containing the α/β phase boundary in 0.1 M NaCl at pH ...

An investigation of micro-galvanic corrosion in Al/AlNp composites
Materials Chemistry and Physics, 2007Abstract In order to investigate the role of aluminum nitride (AlN) in corrosion behavior of Al/AlNp composites, metal matrix composites based on pure aluminum reinforced with AlN particles was prepared. The corrosion behavior of Al/AlNp composites was examined by various techniques.

Susceptibility of rare-earth-magnesium alloys to micro-galvanic corrosion
Corrosion Science, 2010Abstract 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.

Journal of Materials Research and Technology, 2023 The influence of Al–Mn intermetallic on corrosion resistance of AM50 alloy was investigated. TEM-SAED was utilized to identify microstructure and composition of the corrosion products on Al–Mn intermetallic. The electrochemistry results revealed that the corrosion rate of pure Mg was lower than AM50 due to thermodynamic driving force for micro-galvanic
