Journal of Electrochemistry

AC voltammetry,linear sweep voltammetry,and cyclic voltammetry were applied to study the anodic corrosion of Pb,Pb 1.0at%La and Pb 1.0at%Sm electrodes in 4.5 mol·dm -3 H 2SO 4 solution (25 ℃).The experiment results show that samarium can inhibit the anodic corrosion of lead and decrease the impedance of anodic Pb(Ⅱ) film. Lanthanum can also decrease the impedance of the anodic Pb(Ⅱ)film, but the effect is smaller.
