Electrochemical Study of the AISI 409 Ferritic Stainless Steel: Passive Film Stability and Pitting Nucleation and Growth
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2017)
The aim of the present work was to study the passive film stability and pitting corrosion behavior of the AISI 409 stainless steel. The electrochemical tests were carried out in 0.1 M NaCl solution at room temperature. The ...
Effect of citrate ions on the electrochemical behaviour of low-carbon steel in borate buffer solutions
(Elsevier B.V., 2004-03-01)
The electrochemical behaviour of cold-rolled low carbon steel was studied on both active and passive potential regions in borate buffer solutions with and without the addition of sodium citrate (NaCit). In the active region ...
Unexpected effect of citrate ions on the corrosion process of carbon steel in alkaline solutions
(Elsevier, 2017-08-24)
The effect of citrate ions on the passive film stability on carbon steel, at pH 13, was evaluated. The study involved cyclic voltammograms, potentiodynamic polarization curves, micro-Raman spectroscopy and weight-loss ...
Corrosion behavior of Fe-Mn-Si-Cr-Ni-Co shape memory stainless steel in highly oxidizing medium
(2016-01-01)
A study was conducted on the corrosion behavior and characteristics of the passive oxide film of Fe-Mn-Si-Cr-Ni-(Co) shape memory stainless steels (SMSS) in a concentrated nitric acid (HNO3) solution, based on potentiodynamic ...
Carbon steel passivity examined in alkaline solutions: the effect of chloride and nitrite ions
(Pergamon-Elsevier Science Ltd, 2008-06-09)
The effect of chloride and nitrite ions on the passivity of steel in alkaline solutions was investigated. Four nitrite dosages were tested, resulting in various nitrite/chloride ratios. The behavior of steel was evaluated ...
