| Abstract: |
Stainless steel fasteners can fail as a result of stress corrosion cracking (SCC) in coastal atmosphere. In order to have a better understanding of the development of stainless steel fasteners' SCC in marine atmospheric, the corrosion electrochemistry behavior of an austenitic stainless steel contaminated by carbon steel rust component was studied. It was seen that a visible solution film was formed easily on the surface when it was contaminated by carbon steel rust. Pitting and crevice corrosion measurements using smooth and screw specimen show that both the pitting potential and the crevice corrosion sensitive range shift to lower potentials with the increase of chloride ion concentration in the rust. The pitting potential and the crevice corrosion sensitive range under the coverage of carbon steel rust are also lower than that under the coverage of seawater film.
