Abstract
A process for the deposition of a coating on at least a part of a metallic substrate, a) mixing a liquid and a powder having particles of a metallic material to be deposited and particles of a pickling agent, so as to prepare a suspension, b) application of the suspension prepared in step a) to at least a part of the surfaces of the metallic substrate, so as to obtain a substrate-suspension assembly, c) carrying out a heat treatment of the assembly which includes heating at a first temperature of at least 500° C. and heating at a second temperature greater than the first temperature, and d) recovery of a substrate coated, at least in part, with a coating, the pickling agent being a halogenated compound and the suspension having from 10% to 60% of the pickling agent, with respect to the total weight of the powder.
