Journal of Electrochemistry
AC impedance and polarization methods were used to study the inhibition effect of ATA and the complex of ATA and Na2WO4 for brass corrosion in 3% NaCl solution.The results indicated that ATA had inhibition effect for brass corrosion.ATA showed the best inhibition effect for brass corrosion at the ATA concentration of 7.5 mg·L-1,and the inhibition efficiency was 87.46%.At the ATA concentration of 7.5 mg·L-1 and at the Na2WO4 concentration of 0.15 mg·L-1,the complex showed optimum inhibition effect for brass corrosion,and also showed synergistic effect and the inhibition efficiency reached 91.82%.The complex of ATA and Na2WO4 was cathodic corrosion inhibitor.

The Complex Of Pasp And Tungstate As Inhibitors Of Cupronickel B10′S Corrosion In 3% Nacl Solution, Qun-Jie Xu
Journal of Electrochemistry
AC impedance and polarization curve measurements were conducted to study the effects of environ-ment-friendly inhibitors PASP,Na_(2)WO_(4)and their complexes on the corrosion of cupronickel B10 in 3%NaCl solution.The results indicate that PASP or Na_(2)WO_(4)alone does inhibit the corrosion of B10,and most effectiveconcentrations are 40 mg/L and 60 mg/L for PASP and Na_(2)WO_(4),respectively.With the total concentration of 40mg/L for the complex inhibitors,the optimum complex ratio of PASP to Na_(2)WO_(4)was 3:1.The complex of such a combination showed a significantly synergetic inhibition effect on the corrosion of B10.

An Electrochemical Behavior Of Limn_(2)O_(4) Electrode In Electrolyte Based On Room Temperature Ionic Liquid, Zheng Hong-He
Journal of Electrochemistry
The electrochemical behavior of spinel LiMn_(2)O_(4)electrode in ionic liquid electrolyte was investigated by using cyclic voltammetry, galvanostatic charge-discharge and ACimpedance techniques. The results reveal that the spinel LiMn_(2)O_(4)can be effectively cycled in electrolyte based on the ionic liquid with discharge capacity of 108.2mAh/g and Coulombic efficiency of more than 90% in the first cycle at room temperature. Temperature and current density play an important role in the electrode performances. The activation energy for lithium ion transfer through interface between the electrode and the electrolyte was evaluated by AC impedance spectroscopy. The high activation energy accounts for the poor cell performance …
