1. A method for compacting an anti-corrosive paint comprising metal particles of a mechanical part, the mechanical part extending along a longitudinal axis X and comprising a radially external surface, the method comprising a step of spraying a liquid paint loaded with metal particles onto the at least one radially external surface of the mechanical part and a step of polymerization of the liquid paint sprayed so as to form a first layer of anti-corrosive paint intended to protect the part, the method comprising at least one step of generating a laser beam on the surface of the first layer of anti-corrosive paint so as to bring the metal particles into contact and to render the anti-corrosive paint electrically conductive without degradation of the anti-corrosive paint, wherein the anti-corrosive paint is not covered and forms the external surface of the mechanical part.
