应用线性电位扫描法和交流优安法研究了Pb Sn Sm(x(Sn) =0 .0 1,x(Sm) =0 .0 1)和Pb Sn(x(Sn) =0 .0 1)的合金电极在 1.2 8V(vs.Hg/Hg2 SO4 )电位下 ,4.5mol·dm-3 H2 SO4 溶液中的阳极腐蚀 .结果表明 :钐的添加可以阻抑Pb Sn合金的阳极膜的生长并降低阳极膜中Pb(Ⅱ )氧化物的阻抗 .
The relationship between Pb Sn (x (Sn) = 0.01, x (Sm) = 0.01) and Pb Sn (x (Sn) = 0. 01) The results showed that the addition of samarium could restrain the growth of the anode film of Pb-Sn alloy and reduce the corrosion rate of the Pb-Sn alloy in the 4.5 mol · dm-3 H2SO4 solution at 1.2 8V (vs.Hg / Hg2SO4) Impedance of Pb (Ⅱ) Oxide in Anode Film.
