Surface evolution of corroding magnesium : new analytical approaches to understand corrosion mechanisms and protection strategies

Abstract : Nowadays light alloys (Al, Mg) are widely used in a number of areas such as electronics, aeronautic, automotive and construction industries. However, the low corrosion and wear resistance of these alloys hinders application of Al and Mg alloys on a larger scale. The new concepts for corrosion protection of light alloys should include not only barrier protection by a thick oxide layer (PEO) or by paint but also an active protection by specific corrosion inhibitors which can be released “on request” and ensure so-called “self-healing”. Use of in situ and ex situ spectroscopic methods could bring a new view to the evolution of such a complicated system and help to define factors controlling these processes.
