Pitting Corrosion of Ni3(Si,Ti)+4Al Intermetallic Compound at Various Chloride Concentrations

Pitting 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...

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...

Pitting Corrosion Monitoring Using Acoustic Emission

Magnetic behaviour of the intermetallic compound YbCo2Si2

We report on a comprehensive study of the magnetic properties of YbCo2Si2 investigated using a single crystal. All data confirm a stable trivalent Yb state carrying a well-localized 4f moment, as well as a non-magnetic Co state. We observed a sizeable anisotropy in the magnetic susceptibility χ(T ), with the moment in the basal plane twice as large as that along the c-direction. Combining this ...

Numerical Simulation of Material Strength Deterioration due to Pitting Corrosion

Pitting corrosion is an insidious form of localized corrosion a ecting characteristics of various engineering metallic alloys. Currently very limited literature exists with regard to systematic characterization of pitted surfaces or the efficient use of numerical methods to assess its effect, i.e. fatigue life reduction caused by the state of a corroded specimen and particularly through the stu...
