AbstractAcoustic emission (AE) behaviour during the electrochemical corrosion of 304 stainless steel (304SS) in H2SO4 solutions was studied AE signals which related to transpassive dissolution are detected in solutions with low pH and are very slightly influenced by current density and pre-strain During hydrogen bubble evolution a weak correlation exists between the AE signal amplitude and the hydrogen bubble diameter The concept of potential - pH - AE diagram is proposed and such a diagram is drawn based on AE activity and b-values The main mechanisms of AE sources which are transpassive dissolution and hydrogen bubble evolution are also discussed (C) 2010 Elsevier Ltd All rights reserved
