Corrosion Behaviour of Al Based Materials for the Naval Industry

This paper shows the results of the investigation on the corrosion behaviour of in- novative Al- based composite materials. These classes of materials are generally used for engineering applications because of their technological properties as well as rea- sonable cost. Free corrosion and electrochemical tests were carried out in quiescent natural sea water for different exposure times, with the aim of evaluating corrosion attack amount and morphology, general corrosion resistance, as well as susceptibility to pitting corrosion. The corrosion layer was also characterised by different surface analysis techniques.
