Electrochemical noise is naturally generated during corrosion of metals, and can be easily measured by using commercially available potentiostats and zero resistance ammeters. This procedure does not introduce any perturbation to the corroding surface. The measured electrochemical noise can be then analysed to provide invaluable information on the corrosion process.
The new electrochemical noise analysis software, ECN Analysis 1.0, provides a cutting-edge tool to analyse the electrochemical noise data both by statistical methods and Fast Fourier Transform. ECN analysis 1.0 calculates the time evolution of noise resistance, low-frequency noise impedance, charge and frequency of corrosion events based on the user selected parameters (see "Selection of processing parameters").
