Abstract
A method for fabricating a substrate provided with a plurality of layers, includes: providing a steel substrate with an oxide layer including metal oxides on the steel substrate; providing a metal coating layer directly on the oxide layer, the metal coating layer including: at least 8% by weight nickel; at least 10% by weight chromium; and a remainder being iron and impurities from a fabrication process; and providing an anti-corrosion coating layer directly on the metal coating layer.

A method for fabricating a substrate provided with a plurality of layers, the method comprising:
- providing a steel substrate with an oxide layer including metal oxides on the steel substrate;
- providing a metal coating layer directly on the oxide layer, the metal coating layer including:
- at least 8% by weight nickel;
- at least 10% by weight chromium;
- and a remainder being iron and impurities from a fabrication process;
- and
- providing an anti-corrosion coating layer directly on the metal coating layer;
- wherein the providing of the anti-corrosion layer includes depositing the anti-corrosion layer by an electro-deposition process.
