摘要
铅合金由于在硫酸体系中稳定性好而广泛应用于湿法冶金电沉积工序。铅合金的耐腐蚀性能不仅影响生产成本,还会影响阴极产品质量,因此耐腐蚀性能是评价铅合金优劣的关键因素。简要综述了铅合金的晶粒尺寸,二次相形貌及分布和轧制对其腐蚀行为的影响。总结了具有理想耐腐蚀性能的铅合金的微观结构的特征,并对铅合金晶界工程和微区腐蚀行为研究提出了展望。
Lead alloys have been widely applied in hydrometallurgical electrowinning industry due to their high stability in H2SO4 system.Their corrosion resistance not only affects the cost,but also determines the quality of cathode product.Hence,corrosion resistance is a critical factor to evaluate the performance of lead alloys.The effects of grain size,morphology and distribution of second phases,and rolling process on their corrosion behavior are briefly reviewed.The microstructure feature of lead alloys with ideal corrosion resistance is summarized,and the prospects of grain boundary engineering and micro-analysis of localized corrosion behavior of lead alloys are also proposed.
