Abstract
A method for making a multilayer coating on a surface of a substrate by means of at least one thermal spraying method, wherein the following successive steps are carried out:
- a) a first nanostructured or finely structured layer (21) of a first material is deposited on the surface of the substrate (20) by means of a thermal spraying method via a liquid route; the surface of the substrate (20) not having been subject, prior to the deposition of the first nanostructured or finely structured layer (21), to any preparation or activation treatment other than an optional cleaning treatment;b) a second microstructured layer (22) of a second material is deposited on the first nanostructured or finely structured layer (21) by means of a thermal spraying method.
