1 Introduction Local probe scanning electrochemical techniques have attracted significant attention over recent decades due to their ability to investigate electrochemical processes at the micro- and nanoscale [1-4]. Most studies rely on scanning electrochemical microscopy (SECM) [1, 3, 5] or related techniques [6-9], which use microelectrodes as local probes to characterize the reactivity of heterogeneous interfaces.

Abstract Additively manufactured high strength aluminium (Al) alloy AA7075 was prepared using selective laser melting (SLM). High strength Al-alloys prepared by SLM have not been widely studied to date. The evolution of microstructure and hardness, with the attendant corrosion, were investigated. Additively manufactured AA7075 was investigated both in the “as-produced” condition and as a function of artificial ageing. The microstructure of specimens prepared was studied using electron microscopy.

This section will discuss the different alternatives systems designed since the 1980s, and will particularly focus on their main advantages and limitations. The mechanistic aspects involved in each system are summarized in Table 1. The most promising technologies and their associated corrosion protection mechanisms (namely Li-containing coatings, MgR primers and nanocomposites coatings are illustrated in details in Fig. 3).
