ANTI-CORROSION TREATMENT OF A METAL SUBSTRATE AND RESULTING SUBSTRATE

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,...

Beschreibung
Zusammenfassung:	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.
