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

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 electron ...
