Recent Status of Research on Corrosion of Low Alloy Corrosion Resistant Steel and Analysis on Existing Eroblems

The recent status of research on the corrosion of low-alloy corrosion resistant steel was reviewed with an emphasis on its corrosion performance and passivation behavior, thereafter some relevant corrosion mechanisms were summed up. Then, the research concerning modeling for prediction of the service life for the corrosion resistant steel reinforced concrete structures and the related theoretical basis were introduced in terms of corrosion initiation and corrosion propagation, as well as the unique characteristics of the corrosion resistant steel. Finally, several existing issues about corrosion assessment and life time prediction of the corrosion resistant steel reinforced concrete structures are discussed, and the future trends of investigation in the field were also prospected.
