This study presents research capabilities of dynamic electrochemical impedance spectroscopy (DEIS) as a tool used for instantaneous online monitoring of corrosion processes on the example of aluminum alloy 7075. A borate buffer with admixed chloride ions in a quantity ranging from 0.05 mM to 25 mM was used to represent different types of corrosion attack. The surfaces of sample specimens were evaluated before and after the tests by means of scanning electron microscopy. DEIS was assisted in-situ by cyclic polarization and acoustic emission facilitating detection of corrosion attack.
