The application of anti-corrosion base coating by cataphoretic painting
(KTL) is well known in manufacturing automobile body parts. However the
cataphoretic paint can penetrate only incompletely or possibly not at all
into the gap in the contact areas of the components joined to each other.
This type of gap is conventionally scaled following cataphoretic
painting, in order to ensure corrosion protection for the entire
assembly. The present invention makes it possible to dispense with the
sealing in the production of an assembly of joined conductive components
and nevertheless to ensure a sufficient corrosion protection. By
introducing topographic changes in the components projecting from their
surface in the known contact areas and then joining these components,
they are spaced apart by the projecting topographic changes in such a
manner that during cataphoretic painting the paint wets the entire
surface of the assembly.
