| Popis: | The role of arsenate ions and cathodic charging on the environmentally assisted cracking (EAC) behaviour of a Mg-Mn alloy in 0.6 M NaCl saturated with Mg(OH)(2) was investigated. The stability of the surface film and the repassivation kinetics have been found' to play a critical role in the EAC tendency of the alloy than hydrogen-assisted mechanisms. Cathodic charging was found to be beneficial in lowering the EAC tendency of the alloy. (C) 2016 Elsevier Ltd. All rights reserved. |
