摘　　要：铅合金良好的耐腐蚀性能与电催化性能,使其在湿法冶炼材料中应用广泛。在湿法冶炼领域,不同组织结构的铅合金的耐腐蚀性能在影响生产成本的同时,对阴极产品质量也起着重要的作用,而其电催化性能与组织结构也密切相关,因此耐蚀性和电催化活性是评价铅合金性能的重要参考指标。目前铅合金在性能改进方面主要采用合金成分优化与塑性加工变形的方法。简要综述了合金成分优化(主要是铅银合金系列和铅钙锡合金系列)、轧制对铅合金腐蚀行为和电催化行为的影响,并进行了展望。Lead alloys have been widely used in the hydrometallurgy domain owing to their excellent corrosion resistance and electrocatalytic performance.In the field of hydrometallurgy,the corrosion resistance of lead alloys with different microstructures plays an important role in the production cost as well as the quality of cathode products.Furthermore,the electrocatalytic performance of lead alloys is also related to their microstructure.Therefore,the corrosion resistance and electrocatalytic activity of lead alloys are two important reference indicators for evaluating their performance.Currently,strategies for improving the performance of lead alloys are divided into optimization of alloy composition and plastic processing deformation.In this paper,the effects of alloy optimization of alloy composition(mainly Pb-Ag alloy series and Pb-Ca-Sn alloy series)and rolling on the corrosion behavior and electrochemical behavior of lead alloys were briefly reviewed,and the corresponding prospects were made.
