Electrochemical Studies of Pitting Corrosion of Cu-fe Alloy in Sodium Chloride Solutions
The electrochemical studies of pitting corrosion of CuFe alloy (70% Cu30%Fe) were carried out in sodium chloride solutions. The techniques of measurements were: open circuit potential, potentiodynamic polarization and electrochemical impedance spectroscopy. The effect of different concentrations of the inorganic additives (WO4 , PO4 , NO2 , B4O7 , CrO4 ) on the pitting corrosion of the alloy in...
متن کاملPitting Corrosion Behaviour of New Corrosion-Resistant Reinforcement Bars in Chloride-Containing Concrete Pore Solution
In this study, the pitting behaviour of a new corrosion-resistant alloy steel (CR) is compared to that of low-carbon steel (LC) in a simulated concrete pore solution with a chloride concentration of 5 mol/L. The electrochemical behaviour of the bars was characterised using linear polarisation resistance (LPR) and electrochemical impedance spectroscopy (EIS). The pitting profiles were detected b...
متن کاملTHE ROLE OF ALKALINE CLEANING SOLUTIONS AND CL-CONTAINING LUBRICANTS ON PITTING CORROSION IN NiTi ALLOYS
Alkaline cleaning agents are found to react with remnant manufacturing lubricants trapped in surface defects of a NiTi alloy to form Cl-based salts. These sub-surface “reservoirs” may act as nucleation sites for pitting corrosion either latent under ambient conditions, or on exposure to a limited range of high temperatures used to impart pseudoelastic properties in these alloys as part of norma...
متن کاملEffect of Chloride Concentration on the Pitting and Repassivation Potentials of Reinforcing Steel in Alkaline Solutions
Reinforcing steel bars (-12mm diameter and 150mm long) were used in cyclic polarization tests in saturated Ca(OH)z solution and simulated concrete pore solution (SPS) with various levels of sodium chloride addition. Below a limiting chloride level (-O.004M [Cl-] in Ca(OH)z solution and -0.4M [Cl-] in SPS solution), steel was not found to undergo pitting corrosion even if it was polarized to the...
