摘　　要：我国现有材料含有大量的杂质,极大地影响牺牲阳极的电化学性能,采用外国的配方技术、利用我国的原材料,生产不出理想的牺牲阳极材料,在众多的杂质元素中,Fe的含量对牺牲阳极材料的电化学性能影响比较大,研究了Fe含量对铝合金阳极合金材料性能的影响,结果表明:(1)如果Fe的含量过量,此时的铝阳极变成阴极性,在牺牲阳极的铝合金材料内部形成大量微电池,从而恶化牺牲阳极材料的电化学性能;(2)生产牺牲阳极选择铝锭原材料Fe的含量在0.10%附近时,呈现优良的电化学性能。The existing materials in China contain a large number of impurities,which greatly affect the electrochemical performance of the sacrificial anode.The ideal sacrificial anode material can not be produced by using foreign formulation technology and domestic raw materials.Among the many impurity elements,the content of Fe has a great impact on the electrochemical performance of the sacrificial anode material.The effect of Fe content on the performance of the aluminum alloy anode alloy material was studied,The results showed that if the content of Fe was excessive,the aluminum anode became cathodic,forming a large number of micro cells in the aluminum alloy material of the sacrificial anode,which deteriorated the electrochemical performance of the sacrificial anode material.When Fe content of aluminum ingot raw material selected for sacrificial anode production was about 0.10%,it showed excellent electrochemical properties.
