PROCESS FOR THE SURFACE TREATMENT OF ALUMINIUM AND A LAYERWISE CONSTRUCTION OF AN ALUMINIUM COMPONENT HAVING AN ELECTRIC CONTACT

摘要

The invention proposes a process for the surface treatment of aluminum in order to produce an electrical contact, and a corresponding component part, wherein an oxide layer on the aluminum surface is removed, for example by etching, in a first step and, in a second step, before an oxide layer is re-formed, the surface is sealed wet-chemically with a conversion layer having metal ions of zirconium or titanium.
