The kinetics of mild steel corrosion in 20:0, 19:1, 18:2 and 15:5 (v/v%) aqueous mixture of acetic and formic acids has been investigated by weight loss and potentiostatic polarization techniques. The effects of composition of electrolyte and temperature on the corrosion rate of mild steel have been evaluated. The corrosion rate of mild steel increased linearly with temperature as well as amoun...

As a newly developed conductive ceramic with wide application prospects, the electrochemical corrosion behavior of Ti3SiC2 in 3.5% NaCl solution was investigated by potentiodynamic polarization, potentiostatic polarization and electrochemical impedance spectroscopy. Commercially pure titanium (CP Ti) was selected for comparative, and cooperated with XRD, XPS, SEM, the passivation behavior, corr...

The electrochemical characteristics of Ta2O5-IrO2 electrodes prepared from different chemical compositions and coating methods were observed by using cyclic voltammetry, potentiostatic polarization, galvanostatic polarization and scanning electron microscopy. The efficiency for chloride oxidation and oxygen evolution processes was not only influenced by the chemical composition but also by the ...

Electrodialysis is an effective method of water desalination. However, the efficiency of the method is limited by the concentration polarization of the ion-exchange membranes. Applying an electric field with special pulse characteristics can diminish the effect of the concentration polarization. A theoretical analysis is carried out for galvanostatic and potentiostatic pulse regimes. The time d...
