Beschreibung
Zusammenfassung:	The system includes a light metal substrate (1) coated on at least one surface with a protective layer (3) including microparticles (4) containing a fluid active ingredient. Independent claims are also included for use of the protective system in: a) the automobile and sanitary industries and b) with an aluminum substrate for production of aluminum car wheels. Die vorliegende Erfindung betrifft ein korrosionsbeständiges Leichtmetallschichtsystem, das ein Substrat aus einem Leichtmetall, wie z. B. Aluminium, Titan oder Magnesium, enthält, auf das eine Schutzschicht aufgebracht ist, in der Mikropartikel eingebaut sind, die einen flüssigen Wirkstoff enthalten, wobei sich der Wirkstoff bei Freisetzung über die Oberfläche einer Beschädigung in dem Schichtsystem verteilt und so diese Oberfläche vor äußeren Einflüssen schützt.
