In this work the mechanism of etching in a concentrated alkaline solution is studied for two different series of samples, AA3005 and AA6060 aluminium alloys, by mean of electrochemical and surface analysis techniques. The data included here are the results of electrochemical measurements as open circuit potential, polarization resistance, and Electrochemical impedance spectroscopy, surface characterization as Glow Discharge Optical Emission Spectroscopy (GD-OES), Scanning Electron Microscopy and Energy Dispersive Spectroscopy (SEM/EDS). Furthermore, data from Inductively Coupled Plasma Mass Spectrometry (ICP-MS), used to characterize the composition of the etching bath, are also included. The dataset contains TXT, PDF files, and images in JPEG and PNG formats. All the files are contained in subfolders divided on the bases of sample composition and characterization technique.
