Abstract

A method for hard-surfacing metal parts for an aircraft turbofan, the method involving the use of a nozzle outputting a laser beam or an electron beam, which is to heat a sprayed powder for hard-surfacing the metal part, the method including positioning the metal part to be hard-surfaced in an enclosure, the top portion of which has an opening; positioning a mobile cover covering the opening of the top portion, the mobile cover having an opening; positioning the nozzle at the opening of the mobile cover; feeding an inert gas into the enclosure; spraying metal powders and emitting the laser or electron beam for hard-surfacing the metal part; moving the nozzle relative to the enclosure along a path for hard-surfacing the metal part, the movement of the nozzle causing the movement of the mobile cover on the top surface of the enclosure.
