Abstract
In this paper, the influence of the crystallographic orientation of grains on the corrosion behaviour of pure aluminium is investigated combining the Electrochemical Microcell and the X-Ray Diffraction (XRD) Techniques. Crystallographic orientation has strong influence on the current density in the cathodic branch and the breakdown potential. The influence of plastic deformation (compression) on the corrosion resistance is also investigated. Compression has nearly no influence on the current density in the cathodic domain, but improves the corrosion resistance of aluminium in sodium chloride solution.
