Abstract The electrochemical and corrosion behavior of Pb and Pb-In alloys in both phosphoric and sulfuric acid solutions containing various concentrations of phosphoric acid (0.05 to 0.20 M) at different temperatures was studied. Tafel plot and electrochemical impedance spectroscopy (EIS) techniques were used to obtain the experimental data, and the corrosion products formed on the surface were characterized by scanning ...

Effect of indium alloying in various concentrations with lead on both microhardness and crystallite structure of lead-indium alloy was investigated. The corrosion behavior of leadindium alloys in 4 M H2SO4 acid solution was investigated by Tafel plot and electrochemical impedance spectroscopy (EIS) methods. The results of both Tafel plot extrapolation and EIS measurements exhibited the same trend. Generally, the corrosion ... Read more

The influence of indium content on the anodic behaviour of Pb-In alloys in 4 M H2SO4 solution is investigated by potentiodynamic, potentiostatic, chronopotentiometric, and cyclic voltammetric techniques. The composition and microstructure of the corrosion layer on Pb-In alloys are characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy analysis (EDX), and scanning electron microscopy (SEM). The potentiodynamic and chronopotentiometric curves show ... Read more

Abstract The anodic dissolution and passivation processes of zinc and zinc-indium alloys were investigated in an alkaline solution of 6 M KOH using galvanostatic, electrochemical impedance, and charge–discharge measurements. Galvanostatic measurements exhibit anodic potential/time transient of the zinc anode and its alloys in the concentrated alkaline solution at different current densities. The data reveal that the passivation time (tpass.) diminishes ... Read more
