Abstract: The influences of the contents of Sb,As and Ag in the Pb-alloy on its corrosive wei-ght loss, mechanical properties and cyclic voltammograms have been systematically inves-tigated and a proper alloy composition for anodic grid was obtained.Electron beam miero-probe analysis of alloy samples showed that incorporating certain amount of Ag in the Pb-Sb alloy leads to the disappearance of the intercrystalline antimony rich phase.This would be responsible for the improvement of the corrosion-resistance of the alloy.
