Abstract
Process for depositing a corrosion-protection coating on at least one portion of the surfaces of a metallic substrate having at least one cavity with an equivalent diameter emm<2 mm and a length/width ratio of greater than 150, using an aqueous suspension comprising powder of the metal to be deposited on the substrate combined with an agent for protecting the surface of the metal powder, a diluent, and at least one additive, the particles of the suspension each having an equivalent diameter d such that d≤emm/10.
