Zusammenfassung:	A sealing composition for treating parts made of aluminium or aluminium alloy, comprising, in aqueous solution: - a silicate salt, - a functional organosilane belonging to the family of alkoxysilanes of formula: (R1-O)3 - Si - R2 (I) or (R1-O)3 - Si - (CH2)n- O - R2 (II) in which R1 represents a linear or branched alkyl radical comprising from 1 to 5 carbon atoms; n is an integer that can take the values from 0 to 5; R2 represents an alkyl radical, an amine radical or an epoxy radical; and - a phosphate salt. The composition can be used in a method for sealing the porous layer of parts made of aluminium or aluminium alloy in which the parts are immersed in a chromium (III)/zirconium (IV) bath and then in said sealing composition. Composition de colmatage pour le traitement de pièces en aluminium ou en alliage d'aluminium, comprenant, en solution aqueuse : - un sel de silicate, - un organosilane fonctionnel appartenant à la famille des alcoxysilanes de formule : (R1-O)3 - Si - R2 (I) ou (R1-O)3 - Si - (CH2)n- O - R2 (II) dans laquelle R1 représente un radical alkyle linéaire ou ramifié comportant de 1 à 5 atomes de carbone; n est un entier pouvant prendre les valeurs de 0 à 5; R2 représente un radical alkyle, un radical amine ou un radical époxy; et - un sel de phosphate. La composition peut être utilisée dans un procédé de colmatage de la couche poreuse de pièces en aluminium ou alliage d'aluminium dans lequel les pièces sont plongées dans un bain de chrome (III) / zirconium (IV) puis dans ladite composition de colmatage.
