surfaces after anodic potentiodynamic polarization tests. Equivalent circuit was used for modeling the electrochemical impedance spectroscopy (EIS) data, in order to characterize the sample surface... (pH 2.3) at 37 °C. Very low passive current densities (in order of 10-6 A/cm2) were obtained from the anodic polarization curves, indicating high resistances of all samples in acidified 0.9% NaCl......
of small amount gallium (up to 0.06%) on the corrosion behavior of pure aluminum (99.99%,4N) in chloride solution was investigated using a potentiodynamic polarization technique.It has been found...% in the pure aluminum. 关键词:Al-Ga alloy; polarization curve; immersion test; pitting corrosion; [全文内容正在添加中] ......
. The electrochemical properties of the samples were examined using electrochemical techniques: such as open-circuit potential, potentiodynamic polarization curves and electrochemical impedance spectroscopy... corrosion resistance than the Ti12Mo and Cp-Ti in both electrochemical media. Key words: Ti12Mo; Ti60Ta; Cp-Ti; open-circuit potential; potentiodynamic polarization; electrochemical impedance spectroscopy......

of the copper films. The cyclic voltammetry studies reveal that the additives are adsorbed on the electrode surface and inhibit the rate of deposition. Potentiodynamic polarization and electrochemical impedance studies reveal that the deposits produced in the presence of additives display higher corrosion resistance. Key words: electroless copper; additives; potentiodynamic polarization; electrochemical......
and potentiodynamic polarization measurements. The specimens were mechanically polished in cyclohexane with SiC paper down to 600 grit, and polished with 0.5 μm alumina powders. They were then degreased... chemicals and deionized water. Corrosion rates were estimated from the mass loss after immersion in the solutions for durations from one day to a few weeks. Potentiodynamic polarization curves were measured......
measurement, linear and potentiodynamic polarization. The results indicate that the laser-welded NiTi alloy is less susceptible to pitting and crevice corrosion than the base metal, which is demonstrated... linear polarization experiments Fig.3 Corrosion current density calculated during linear polarization experiments 3.3 Cyclic potentiodynamic polarization experiments The cyclic potentiodynamic......
). Potentiodynamic polarization measurement was adopted to investigate the corrosion resistance of samples and the tests were carried out respectively in 1mol/L H2SO4 and NaOH aquatic solution. The corrosion...; corrosion resistance; polarization measurement; [全文内容正在添加中] ......
of warm air. Electrochemical tests were carried out in 1 mol/L NaCl solution using electrochemical impedance spectroscopy(EIS) and potentiodynamic polarization techniques. All experiments..., a large platinum sheet as auxiliary electrode, and the sample as the working electrode. Before EIS and potentiodynamic polarization measurement, the working electrodes were immersed in NaCl solution......
