Beschreibung
Zusammenfassung:	The invention described herein provides an organic-inorganic multilayer coating system comprising an advanced nanostructured layer-by-layer hybrid coating for the corrosion inhibition of metals. Electrochemically-active corrosion inhibitors are adsorbed onto a layer-by-layer assembled organic-inorganic multilayer coating, preferably used in combination with a topcoat sol-gel barrier layer, to provide enhanced corrosion protection of metal substrates. L'invention prote sur un système de revêtement multicouche organique-inorganique comprenant un revêtement hybride couche par couche nanostructuré avancé permettant d'inhiber la corrosion des métaux. Des inhibiteurs de corrosion électrochimiquement actifs sont adsorbés sur un revêtement multicouche organique-inorganique assemblé couche par couche, de préférence utilisés en combinaison avec une barrière sol-gel de couche de finition, afin de fournir une meilleure protection contre la corrosion des substrats métalliques.
