Contribution to the knowledge of the relationship between the electrochemical and corrosion behaviour and the structure of metallic materials subjected to cold plastic deformation

Abstract

AbstractWithin the framework of a systematic study of the effect of cold plastic deformation on the electrochemical behaviour (anodic and cathodic characteristics) and the corrosion behaviour (corrosion rates in the active region, evaluated by the method of Stem and Geary and by loss in weight) of metallic materials, the results relating to the case of austenitic stainless steels AISI 304, 304 L and 316, ARMCO iron and nickel deformed by tension and immersed in de‐aerated sulphuric acid solution are presented and discussed with the aim of interpreting these aspects of their behaviour on the basis of the “structure” of the deformed materials.
