Research on AE-signals of corrosive processes

The paper is aimed at examination of acoustic-emission signals occurring as a result of imitation and growth of local corrosion pits on steel samples in laboratory conditions. The revealed regulations can be used for establishing the assessment criterion of danger level of corrosive damages on various facilities of different application.

In order to reveal the regulations in the way AE-signals’ features correspond to their occurrence pattern during the metal corrosion process, an analysis of statistic data obtained in the experiment was carried out.

The results of the data analysis are parameters of amplitudes and AE-signal lengths corresponded to corrosion processes. The parameters are used in the comprehensive monitoring system COMPACS^®-AE for classification of AE-processes.
