Effect of Samarium on the Corrosion of Lead-tin Alloy in Sulfuric Acid Solution at the Floating Charge Potential
【摘要】 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 .
【Abstract】 The corrosion of Pb-Sn-Sm(x(Sn)=0.01,x(Sm)=0.01) and Pb-Sn(x(Sn)=0.01) in 4.5 mol·dm -3 H 2SO 4 solution at 1.28 V(vs.Hg/Hg 2SO 4) have been studied using linear sweep voltammetry and ac. voltammetry. The experimental results show that the samaium added to Pb-Sn alloy can inhibit the growth of the anodic film and reduce the resistance of the Pb(Ⅱ) oxides in the film.
