Abstract

Structural and electrochemical analysis of rust formed from low alloy steel was performed. The samples, generated in the framework of MICAT project, were exposed in two marine environments: subtropical and sub polar Antarctic. The results suggested the formation of oxides and oxihidroxides of low crystallinity and poor protective properties. The evolution of the results is analyzed tacking to account the different environments. The electrochemical activity and phases concentration of corrosion products are analyzed by cluster diagrams with the objective of adjusting qualitative models.
