Corrosion monitoring of the AA2024 alloy in NaCl solutions by electrochemical noise meassurements
Keywords:AA2024, EIS, ENM, Chaos
The behaviour of the AA2024 alloy against corrosion in 3.5 % NaCl solution has been monitored. In this environment the alloy can be easily damaged under small anodic polarizations. Linear polarization, electrochemical impedance, spectroscopy and electrochemical noise meassurement have been used as experimental techniques. Data from ENM have been analized using statistical parameters and Chaos Theory. The results here obtained suggest that ENM is particularly useful to monitor systems that can be modified using other electochemical techniques.
