【Abstract】 The corrosion-resistance properties of new grid alloy and traditional alloy were studied using anodic polarization curve and A.C.impedance.The anodic films of comparative alloys formed in sulfuric solution at anodic 0.9 V potential corrosion for 6 h were investigated by means of XPS and XRD methods.The result showed that new grid alloy has better corrosion-resistant behavior than that of traditional alloy,the growth of Pb（Ⅱ） dioxide in new alloy surface layer was inhibited.By means of A.C.impedance method,the resistor of the corrosion layers were decreased,it was found that the new alloy can encourage the development of PbO₂ in the scale,and enhance the conductivity of the anodic scale,then,the deep recycling properties of the battery was promoted greatly.The new alloy can serve as the candidate for the grid material in maintenance-free lead/acid battery.更多还原
