摘　　要：鉴于铝基体优越的导电性、强度比和耐氧化酸性,新型铝基铅合金惰性阳极材料已经成为湿法冶金阳极材料研究热点之一。本文将研究轧制、铝基界面镀锡和阳极氧化、表面压花等不同处理工艺对Al/Pb-0.3%Ag惰性阳极组织和综合使用性能的影响。结果表明,不同处理工艺对Al/Pb-0.3%Ag合金阳极组织形貌、力学性能、界面相容、电化学腐蚀以及表面物相组成有着不同的影响。其中阳极氧化-轧制-压花处理Al/Pb-0.3%Ag合金阳极晶粒细小均匀,界面相容好,具有良好机械性能和电化学耐蚀性能。Due to the excellent conductivity,strength ratio and resistance to oxidizing acid of alumi‐num matrix,new composite lead alloys inert anodes on aluminum substrates have become one of the re‐search hotspots in hydrometallurgy.In this paper,the effects on the microstructure and comprehensive performance of Al/pb-0.3% Ag inert anodes were studied in rolled,tin plated and anodized to interface and surface embossing pretreatment process.The results show that different pretreatment processes have different effects on the morphology,mechanical properties,interfacial compatibility,electrochemical corrosion and surface phase composition of Al/Pb-0.3% Ag composite inert anodes.The Al/Pb-0.3% Ag composite inert anodes prepared by anodized-rolled-embossed have fine and uniform grain size,good interface compatibility,good mechanical properties and electrochemical corrosion resistance.
