摘　　要：本文通过对三种化成铝箔采用SEM与EDS技术工具分析,分析研究三种低压阳极化成铝箔的形貌与组分,并用该三种铝箔制作100V/47u F低压电容器,进而进行耐久性试验比较分析,对化成铝箔氧化膜形貌与电容器性能的影响关系进行研究,试验比较发现,氧化膜对铝电解电容器寿命的影响较大,主要表现在氧化膜上的羟基过多,影响漏电流。This article through the analysis using SEM and EDS technology of three kinds of tools to foil,analysis of morphology and group study of three kinds of low pressure anode foil is divided into three kinds,and the production of 100V/47 u F aluminum foil for low voltage electrolytic capacitor,and durability tests carried out comparative analysis,to study the effects on the formation of aluminum foil oxide film morphology and capacitor the relationship between the performance of test,comparison,effect of oxide film on aluminum electrolytic capacitor life greatly,mainly in the oxide film of the hydroxyl groups on the excessive influence of the leakage current.
