摘要
通过掺杂不同含量的Pr对低锑铅合金的电极电位以及相关力学性能进行改性研究,采用恒流极化、LSV、拉伸等实验测试各合金的电极电位及相关力学性能。结果表明,加入0.8%(质量分数)Pr后,Pb-Sb合金的抗拉强度提高32.66%;由于Pr能降低析氧过电位,使得Pb-Sb合金的阳极电位有一定程度的下降。Pr对低锑铅合金阳极主要性能均有较大程度的改进作用,是很好的阳极改性剂,具有较好的工业应用前景。
The effects of different Pr additions on the main properties(anode potential and mechanical property)of low antimony lead alloy anode for zinc electrowinning used in galvanizing were investigated by using constant-current polarization?LSV and mechanics performance testing.The results show that0.8wt%Pr addition can enhance the tensile strength of Pb-Sb alloy about32.66%.Furthermore there is a certain degree to decline the anode potentials of Pb-Sb alloy due to the Pr reduction of over-potential of oxygen evolution.Therefore,Pr is a good modifier for zinc electrowinning anode which can improve the main properties of low antimony lead anode.
