AB  - Electrochemical studies were performed on LaNi4.15Co0.43Mn0.40Fe0.02. alloy electrode. The kinetics of the electrochemical hydrogen absorption/desorption reaction was studied by DC polarization and AC impedance measurements. In a low overpotential range the reaction is charge-transfer controlled while in a high-overpotential range, the combine mechanism, charge-transfer and hydrogen diffusion in the bulk of the alloy is operative. Both exchange current, I-0, and hydrogen diffusion coefficient, D, slightly increase with hydrogen concentration in the alloy electrode.

AB  - The corrosion behavior of mild steel covered by electrodeposited polypyrrole films was investigated by electrochemical impedance spectroscopy. Electrodeposition of polypyrrole was performed from an aqueous solution of pyrrole and oxalic acid at a constant current density of 1 mA/cm(2) and yields strongly adherent and smooth polymer layers. The non-linear least squares (NLS) fitting was applied to the impedance spectra to estimate the parameters of the proposed equivalent circuit, based on a physical model for the corrosion of mild steel protected by polypyrrole films in acid sulfate solutions.

AB  - The kinetics and mechanism of hydrogen evolution at Ti-Ni alloys electrode has been studied by means of steady-state potentiostatic polarization and ac impedance spectrum measurements. Complex-plane spectrum plots are derived for the h.e.r. at one of the most inactive, typical hydridic, Ti-Ni, and one of the most active, typical electrocatalytic, Ti-Ni-3, intermetallic alloy compounds at various potentials. The rate constants of the forward and backward reactions of the corresponding steps were estimated by a nonlinear fitting method. It has been found that the overall reaction proceeds through a coupled Volmer-Heyrovsky mechanism. The electrocatalytic activity decreases in the order TiNi2  gt  TiNi3  gt  TiNi4  gt  Ti2Ni  gt  TiNi  gt  Ti3Ni  gt  TiNi0.7.

AB  - The kinetics and mechanism of hydrogen evolution at Ti-Ni alloy electrodes prepared by are-melting and mechanical alloying methods has been studied by means of AC impedance spectrum measurements. The electrode, prepared by mechanical alloying (porous electrode), after activation in a 10% HF solution, is very active despite its large Tafel slope. The SEM studies show a formation of deep pores on the electrode surface. The rate constants of the forward and backward reactions of the corresponding steps were estimated by a nonlinear fitting method. It has been found that the overall reaction proceeds through a Volmer-Heyrovsky mechanism.
