A novel chloride stress corrosion cracking CSCC test was carried out on AISI 304L: the imposition of an anodic potential to shorten the test duration time. A stress is applied to promote cracks. Acoustic emission (AE) methods were used to characterize and monitor the phenomena. The degradation of the material was characterized by coupling of acoustic emission and electrochemical measurements. The evolution of current density and applied load was monitored to make links between the AE results and the various stages of CSCC. The fracture faces and the corrosion were observed by optical microscopy and SEM. (C) 2016 Elsevier Ltd. All rights reserved.
