in aqueous electrolytic media," Journal of Materials Engineering and Performance, vol.
At the beginning of the experiment, the slope of cathodic polarization
curve was larger than that of anodic polarization curve.
ORR process on Pt-electrode in 0.1 M KOH for cathodic polarization
of 1.1 to -0.2 V (versus RHE) is accompanied by ring/disk current ratio within 20-25% interval .
Figure 1(a) displays the cathodic polarization
curves of [Emim][DCA] containing 0.05 M Sn(II), 0.1 M Cu(I) + 0.05M Sn(II), and 0.1 M Cu(I).
Since the anodic peak on the voltammogram occurs only after the cathodic polarization
of the CPE, it is most likely associated with the electric oxidation of iron(II) to iron(III) from the nanoparticles to the CPE surface.
In cathodic polarization
the voltage increases with the corrosion current decreases until it reaches the lowest possible value.
The sacrificial zinc in the primer provides short-term protection to the exposed steel from corrosion through cathodic polarization
, providing sufficient time for the silane to form an effective barrier layer.
The Icorr was determined by Tafel extrapolation of only the cathodic polarization
curve alone, which usually produced a longer and better defined Tafel region .
at Uncharged Surface Potential as the Way of Protection from Corrosive-Mechanical Destruction in Sea Water.
The anodic and cathodic polarization
curves, according to ISO 17475, were recorded using two separated sweep potential scans in the range [+ or -] 1500 mV respect OCP with a scanning rate of 1 mV/s.
A cathodic polarization
measurement was carried out to evaluate the role of citric acid.
In addition, the obtained results revealed that the cathodic polarization
curve of Zn--Ni--Fe alloy deposition (29) lies between the polarization curves of Zn and Ni or Zn and Fe.
