Abstract
Aluminium alloys may suffer from severe localized corrosion as a result of their relatively complex and heterogeneous microstructure. The corrosion initiation in these critical alloys is governed by dynamic processes that take place at the nanoscale. A thorough understanding of the sequential stages of corrosion initiation is of pivotal importance to develop efficient corrosion protection strategies and demands high-resolution techniques along with the ability of real-time recording of nanoscopic events. Recently, we have shown the dynamic evolution of site-specific local corrosion of aluminium alloys during early initiation stages at the nanoscale using dedicated in-situ liquid phase-transmission electron microscopy (LP-TEM). However, these studies are not straightforward and there are limitations and challenging experimental considerations for conducting reliable examinations. Herein, challenges as well as achievements in in-situ and nanoscopic corrosion studies using LP-TEM are presented and discussed.
