Zusammenfassung:This work focuses on the photoelectrochemical and semicondictrise study of the corrosion layer formed in the dark on Pb and PbSn alloys in a 0.5M H2SO4solution: Electrochemical Impedance Spectroscopy (EIS), Linear Sweeping Voltage (LSV), Mott-Schottky plots and photocurrent measurements. The composition was determined respectively by XRD diffraction and SEM electron microscopy. The results showed that tin reduces the thickness and improves the conductivity of the corrosion layer by forming conductive and non-photo-active tin oxides and a dense layer between the grid and the positive active mass.
