Film composition and percentage of atom were analyzed by XPS,voltage-time response of aluminum foil during anodizing was followed,dielectric constant of composite films was calculated in theory,and capacitance and durability of aluminum electrolytic capacitors was.

Anode aluminum foil is the key material for manufacturing aluminum electrolytic capacitors, and the size and application of aluminum electrolytic capacitors strongly depend on the properties of the anodic oxide film formed on which.

High specific surface area can be obtained after electron aluminum foil is etched.

and parameters of heat treatment process on mechanical property of aluminum foil for electric cable are determined.

The effect of middle annealing on the evolution of textures in high voltage aluminum capacitor foils was investigated by means of orientation distribution functions (ODFs).
