Corrosion protection of Aluminium unpainted parts: development of an appropriated Cr free sealing process on thin SAA layer (≤5 µm) (SAA-Seal)
Date du début: 1 mai 2012, Date de fin: 30 avr. 2014,
Corrosion of Al has to be counteracted by first anodizing the Al parts and applying further protective coatings. During anodizing, Al reacts with the electrolyte and a layer of aluminium oxide is formed, which is highly porous and is subject to corrosive attack. Therefore, anodized Al is normally further processed with a sealing as a final step. Sealed SAA industrial processes providing thicker la ...

Chromate free and energy efficient sealing of TSA anodic films for corrosion protection (TARTASEAL)
Date du début: 1 déc. 2011, Date de fin: 30 nov. 2012,
"Corrosion of Al has to be counteracted by first anodizing the Al parts and applying further protective coatings. During anodizing, aluminium reacts with the electrolyte and a layer of aluminium oxide is formed on the surface of the aluminium specimen. This coating is highly porous and is subject to attack from the environment and corrosive elements. Therefore, anodized aluminium is normally furth ...
