Abstract
A method for additive manufacturing deposits material on a part forming a substrate, wherein the part forming a substrate is made of a metal alloy. The method includes a step of low-energy deposition corresponding to a surface energy of less than 400 J/mm2, on a predefined surface to be deposited, in order to form a base layer. The method further includes a step of high-energy deposition, corresponding to a surface energy greater than 500 J/mm2, by depositing a wire on the base layer already formed.
