SOL-GEL METHOD FOR PRODUCING AN ANTI-CORROSION COATING ON A METAL SUBSTRATE
The invention relates to a sol-gel method for producing an anti-corrosion coating consisting of at least one layer (31, 32) of an oxide on a metal substrate (10). A non-aqueous solution (1) of a precursor of the oxide is prepared (SI) and deposited (S2) on one surface (11) at least of the metal subs...

| description | The invention relates to a sol-gel method for producing an anti-corrosion coating consisting of at least one layer (31, 32) of an oxide on a metal substrate (10). A non-aqueous solution (1) of a precursor of the oxide is prepared (SI) and deposited (S2) on one surface (11) at least of the metal substrate in order to cover said surface at least partially with a film (20) comprising the precursor of the oxide. Hydrolysis-condensation of the precursor of the oxide is carried out (S3) by exposing the film to a humid atmosphere in order to form an oxide network in the film. Then, a treatment for stabilising the film on the surface of the substrate is carried out (S4), followed by a heat treatment (S5) of the surface of the metal substrate in order to crystallise the network of oxide and form the anti-corrosion coating.
L'invention se rapporte à un procédé sol-gel de fabrication d'un revêtement anticorrosion constitué d'au moins une couche (31, 32) d'un oxyde sur un substrat métallique (10). Une solution non-aqueuse (1) d'un précurseur de l'oxyde est préparée (SI) et déposée (S2) sur une surface (11) au moins du substrat métallique pour recouvrir au moins partiellement ladite surface par un film (20) comprenant le précurseur de l'oxyde. Une hydrolyse-condensation du précurseur de l'oxyde est réalisée (S3) par exposition du film à une atmosphère humide afin de former un réseau d'oxyde dans le film. Ensuite, un traitement de stabilisation du film sur la surface du substrat est effectué (S4), suivi d'un traitement thermique (S5) de la surface du substrat métallique pour cristalliser le réseau d'oxyde et former le revêtement anticorrosion. |
