英语. This work focuses on the photoelectrochemical and semicondictrise study of the corrosion layer formed in the dark on Lead and lead-tin alloys in a 0.5M sulfuric acid solution: 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 findings indicate that the incorporation of tin leads to a reduction in the corrosion layer thickness while significantly enhancing its electrical conductivity. This effect is attributed to the formation of conductive, non-photoactive tin oxides and the development of a compact interfacial the layer separating the grid from the positive active material.

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.
