Description
The dataset contains the cyclic polarization studies and corresponding acoustic emission measurements, revealing the pitting corrosion process of the passive layer at the surface of the 7075 aluminum alloy in the borate buffer with different chloride ions concentrations, in the range between 0.05 and 25 mM.
AE signal was recorded using a 2-channel Vallen AMSY-4. It is composed of an analog/digital measurement card with a digital signal processor and specialized software for online signal recording and analysis. A piezoelectric transducer was used. The sensor was connected to the card through an AE pre-amplifier. The applied gain was 60 dB, with the threshold value set to 27 dB. AE tests were conducted during cyclic polarization, which allowed correlating acoustic activity of the alloy with polarization results. Cyclic polarization and EIS measurement setup were composed of Gamry Instruments CMS-3001† system. The scan rate was equal to 1 mV/s.
