ANTI-CORROSION TREATMENT OF A METAL SUBSTRATE AND RESULTING SUBSTRATE

摘要

A method of treating a metal substrate with an anti-corrosion coating comprising at least the following steps: preparing a solution comprising particles of a precursor of the oxide, dipping at least one surface of the metal substrate into the prepared solution and then removing it from the solution, heat treating the surface of the metal substrate in order to generate oxide nanocrystals from the particles of the precursor and form the anti-corrosion coating, and forming a natural oxide layer between the metal substrate and the anti-corrosion coating, the natural oxide layer being enriched with elements from the oxide nanocrystals of the anti-corrosion coating.

1. A method for treating a metal substrate with an anti-corrosion coating composed of a single layer of oxide nanocrystals deposited on the metal substrate, the method comprising at least:
preparing a solution comprising particles of an oxide precursor; dipping at least one surface of the metal substrate into the prepared solution and then withdrawing it from the prepared solution in order to cover said at least one surface of the metal substrate at least partially with particles of the oxide precursor; heat treating the at least one surface of the metal substrate in order to generate oxide nanocrystals from the particles of the oxide precursor and form the anti-corrosion coating; and forming a natural oxide layer between the metal substrate and the anti-corrosion coating, the natural oxide layer being enriched with elements from the oxide nanocrystals of the anti-corrosion coating.
