Abstract (en)
[origin: WO2021083694A1] The invention concerns a method for depositing a coating on at least one part of a metal substrate, said method comprises the following successive steps: a) mixing a liquid and a powder comprising particles of a metal material to be deposited and particles of a stripping agent in order to prepare a suspension, b) applying the suspension prepared in step a) on at least one part of the surfaces of the metal substrate so as to obtain a substrate/suspension assembly, c) carrying out a heat treatment of the substrate/suspension assembly comprising heating to a first temperature of at least 500°C and heating to a second temperature greater than the first temperature, and d) recovering a substrate at least partially coated with a coating, the stripping agent being a halogenated compound and the suspension comprising 10% to 60% by weight of the stripping agent relative to the total mass of the powder.
