Abstract (en)
[origin: WO2018115207A1] 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.
