The electrode impedance determined experimentally shows a certain number of time constants as capacitive or inductive features. These impedances arise from various processes occurring at near the interface, such charge transfer, adsorption‐desorption reaction intermediate species, changes roughness factor, active sites volume concentration in vicinity electrode, etc. origins are examined on basis experimental results given Part I . Then, hypotheses describing rates, Tafel law, reversibility,...
The dissolution of copper in 1M chloride solution was studied by steady‐state (current‐voltage curves for various disk rotation rates) and transient [frequency analysis the electrochemical electrohydrodynamical (EHD) impedance] measurements. anodic polarization have presented one region mixed kinetic another mass‐transport control characterized a current plateau. limiting is function throughout whole range rates. From EHD impedance diagrams observed below plateau, it shown that limitation...
The mechanism of Zn‐Ni alloy deposition in acidic sulfate electrolytes is analyzed essentially from polarization curves and impedance plots, using a rotating disk electrode. anomalous the zinc‐rich phases γ δ occurs at high cathodic polarizations, nickel being inhibited zinc stimulated. At low nickel‐rich deposits are formed, on which diffusion‐controlled hydrogen evolution predominates, pH 1.5. transition shown to be related with both an increase interfacial presence sulfur deposit....
The dissolution of copper in 1 M chloride solution was studied by steady‐state (current‐potential curves for various disk rotation rates) and transient measurements [frequency analysis the electrochemical electrohydrodynamical (EHD) impedance]. anodic polarization present four regions according to potential: one region mixed kinetics followed another mass‐transport control characterized plateau, a second plateau. results obtained first domain plateau were previously published. In this work,...
