Testing HIADAC high impedance analyzer in Trento University laboratory on protective foil using 2-wire probe 48h exposition

Description

The dataset presents impedance spectrum of anticorrosion foil (coating) protecting aluminium frame . This object was used to test high-impedance analyzer for diagnostic of anticorossion coatings (HIADAC) realized in the frame of Eureka project E!3174. The impedance spectrum frequency range (0.1 Hz – 100 kHz) was selected in order to test the whole measureement range of the analyzer. In this dataset, the DC polarisation was automatically set to compensate open-circuit potential and AC amplitude was set to 20 mV. The model together with the 2-wire measurement probe (dedicated for grounded objects) was placed in Faraday cage. The measurement setup is presented in the photo below. The spectrum was acquired after 48 hours of exposition on 3% NaCl solution.

Top-left figure presents impedance modulus and top-right figure presents impedance angle for the measurements done using the setup presented in bottom-left figure (in the central part HIADAC could be seen).
