Abstract

Aluminiumfolier benyttet som materiale til elektroder i elektrolytiske kondensa- torer fremstilles ved en fremgangsmåte hvorved et overflateparti av aluminium- folien først fjernes før folien senere etses elektrokjemisk eller kjemisk. Deretter dannes et initialt indre oksidbelegg 5-50 A tykt på overflaten hvorfra overflatepartiet er blitt fjernet. Deretter blir aluminiumfoliene utsatt for høytemperatur-varmebehandling slik at den totale tykkelse av oksid- belegget ikke overskrider 70 A.Aluminum foils used as material for electrodes in electrolytic capacitors are produced by a process whereby a surface portion of the aluminum foil is first removed before the foil is subsequently etched electrochemically or chemically. Thereafter, an initial inner oxide coating 5-50 A thick is formed on the surface from which the surface portion has been removed. Then, the aluminum foils are subjected to high temperature heat treatment so that the total thickness of the oxide coating does not exceed 70 A.
