Abstract: The invention concerns a method for the surface treatment of a component, for example a turbomachine component, the component comprising a surface to be treated, the method comprising the following steps: loading a first dispenser with a chemical etching solution and a second dispenser with a rinsing solution, positioning the first dispenser and the second dispenser opposite the surface to be treated, moving the first dispenser and the second dispenser along the surface to be treated, such that the surface to be treated successively receives the chemical etching solution followed by the rinsing solution.

Abstract: A method compacts an anti-corrosive paint having metal particles of a mechanical part such as a turbine engine part. The mechanical part extends along a longitudinal axis X and has a radially outer surface covered with a first layer of anti-corrosive paint. The method includes at least one step of generating a laser beam on the first layer of anti-corrosive paint to bring the metal particles into contact and to render the anti-corrosive paint electrically conductive.

Abstract: A blasting medium includes first ice particles and second particles having a hardness between 2000 and 2500 HV. The second particles are embedded in the surface and in the volume of the first particles.

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.

Abstract: A method for treating an internal defect in a part made of a material, involves: a) detecting and locating the internal defect in the part; b) defining, inside the part, at least one target volume which at least partially includes the defect; c) for each target volume, simultaneously irradiating the target volume by at least two beams which converge in the target volume and are continuous, whereby a treated area is obtained. The energy applied to the target volume by each beam is less than a threshold energy for sintering the material, and the sum of the energies applied to the target volume by each of the beams is greater than or equal to a transformation threshold energy that corresponds to the threshold energy for sintering or melting the material; the material of the part is partially transparent to said beams.
