Process for the production of an anode for an electrolytic capacitor |
摘要 |
An anode for an electrolytic capacitor includes aluminum foil as a substrate. On the aluminum foil is an alloy including aluminum and a further metal whose oxide has a higher dielectric constant than aluminum oxide. This alloy increases the surface roughness and is in vapor deposited in vacuum in several process steps at different angles of incident. A porous layer thereby is formed and a subsequent anodic oxidation is carried out.
