On the corrosion behavior of Al2Cu by local electrochemical impedance spectroscopy using droplet cell microscopy

A Summary of Corrosion Properties of Al-Rich Solid Solution and Secondary Phase Particles in Al Alloys

“…One very successful method for determining the corrosion characteristics of secondary phase particles is the electrochemical microcell method, which uses a small capillary filled with electrolyte, the tip of which permits electrochemical analysis of specific particles [11,[35][36][37][38][39][40]. This method has been employed with both synthesized intermetallic compounds (IMCs) and/or actual alloy substrates [11,17,34,[41][42][43][44][45][46][47].…”

Small-Area Techniques for Micro- and Nanoelectrochemical Characterization: A Review

“…A number of terms were employed to denote this technique. They are "micro-cell", 48 "electrochemical micro-cell", 49 "capillarybased droplet cell", 50 "micro-droplet cell", 51 "microcapillary electrochemical droplet cell", 52 "capillary electrochemical micro-droplet cell", 53 "droplet cell microscopy", 54 "microcapillary electrochemical cell", 55 and "electrochemical droplet cell". 56 Herein, terms like "SDC" and "droplet cell microscopy" (DCM), both of which belong to the MCC technique, are used to stand for free droplet cell technique and the contact mode technique, respectively.…”

Orthophosphoric acid solutions of sodium orthovanadate, sodium tungstate, and sodium molybdate as potential corrosion inhibitors of the Al2Cu intermetallic phase

“…The same effect was reported in the literature for Al 2 Cu immersed in 0.1 M NaCl solution. The high electrical double-layer capacitance was attributed to the formation of hydroxide ions on the surface due to the oxygen reduction reaction [47]. 0.5 M H 3 PO 4 /0.2 M Na 3 VO 4 and 0.5 M H 3 PO 4 /0.2 M Na 2 WO 4 solutions were then acidified to pH = 1.0.…”
