Abstract: The α-PbO deposition layers were prepared on the surface of Al/Pb substrates by constant current electrosynthesis from

an alkaline bath, and Al/Pb/α-PbO2 composite inert anode materials were obtained. The effects of the bath composition and bath
temperature on the electrosynthesis of α-PbO2 were investigated by means of anodic polarization method, the phase structures and
surface microstructures of Al/Pb and α-PbO2 deposition layers were tested by means of X-ray diffraction (XRD) and scanning
electron microscopy (SEM), respectively. The experimental data have shown that the process of α-PbO2 formation have several
stages. The
