A Chromium-free conversion coating is prepared by the addition of inorganic salts to dispersions of conducting polymers which are then exposed to alloys of aluminum or other metals. Advantageously, the performance of our inventive coating is comparable to that of conventional Cr-based methods for a number of aluminum alloys having particular significance in the manufacture of aircraft.
La présente invention concerne un revêtement de conversion dépourvu de chrome qui est préparé par l'addition de sels inorganiques à des dispersions de polymères conducteurs, qui sont ensuite exposées à des alliages d'aluminium ou d'autres métaux. De façon avantageuse, la performance de notre nouveau revêtement est comparable à celle des procédés classiques à base de Cr pour un certain nombre d'alliages d'aluminium ayant une importance particulière dans la fabrication d'aéronefs.
