Abstract
A sol-gel method for producing an anti-corrosion coating consisting of at least one layer of an oxide on a metal substrate. A non-aqueous solution of a precursor of the oxide is prepared and deposited on one surface at least of the metal substrate in order to cover said surface at least partially with a film comprising the precursor of the oxide. Hydrolysis-condensation of the precursor of the oxide is carried out by exposing the film to a humid atmosphere in order to form an oxide network in the film. Then, a treatment for stabilizing the film on the surface of the substrate is carried out, followed by a heat treatment of the surface of the metal substrate in order to crystallize the network of oxide and form the anti-corrosion coating.
