Abstract (en)
The method for making a protective coating on a metal substrate including nickel atoms comprises the steps of : electro-chemical deposition of an aluminum layer on the substrate using a bath consisting of a ionic liquid comprising a chloroaluminate anion and an organic cation, and vacuum heating of said substrate on which the aluminum layer has been deposited, such that nickel atoms migrate from the substrate to the aluminum layer, with the formation of a nickel-aluminum alloy-based protective coating.
