Annotation	This work investigates the possibilities of monitoring ongoing corrosion process by acoustic emission (AE) and of determining overall corrosion damage by the nonlinear wave modulation spectroscopy method (NWMS). Specimens made of Al-alloy L-beams simulating stringer reinforcements of airplane structure were studied. The samples were repeatedly immersed in sea salt solution. The acoustic emission activity was recorded in situ during corrosion process. Nonlinear parameters of the samples were measured in between corrosion tests by NWMS method. The current dynamics of a corrosion process was determined by AE, the amount of corrosion damage was corresponding to the nonlinear parameters obtained by NWMS.
