Abstract:In this work, the output of different accelerated tests on anodic aluminum oxide (AAO) coatings developed on AA5005 aluminum alloy (sulfuric acid bath and hydrothermal sealing) has been investigated. In particular, three corrosion testing methods, namely neutral salt spray test (NSS), acetic acid salt spray (AASS) and prohesion test, have been performed on the sealed AAO-coated panels in order to investigate the reliability of the obtained results to the electrochemical impedance ones. NSS and prohesion testin… Show more
