Title
(EN) HYBRID LASER PLUS SUBMERGED ARC OR ELECTROSLAG CLADDING OF SUPERALLOYS
(FR) PLACAGE DE SUPERALLIAGES PAR LASER HYBRIDE PLUS ARC SOUS FLUX EN POUDRE OU LAITIER ÉLECTRO-CONDUCTEUR
Abstract
(EN) A method for cladding of superalloy materials. A layer of powder (14) disposed over a superalloy substrate (12) is heated with an energy beam (16) to form a layer of superalloy cladding (10) and an overlying layer of slag (18). A filler material (44) of nickel, nickel-chromium or nickel-chromium-cobalt wire or strip is also added to the melt pool to combine with the melted powder via a submerged arc or electroslag heating process to give the superalloy cladding the composition of a desired superalloy material. The layer of powder includes a layer of powdered flux material (22) over a layer of powdered metal (20), or the flux and metal powders may be mixed together (36).
(FR) L'invention concerne un procédé destiné à plaquer des matériaux en superalliage. Une couche de poudre (14), disposée sur un substrat (12) en superalliage, est chauffée par un faisceau d'énergie (16) pour former une couche de placage (10) de superalliage et une couche surjacente de laitier (18). Un matériau d'apport (44) sous forme de fil ou de bande de nickel, nickel-chrome ou nickel-chrome-cobalt est aussi ajouté à la flaque de fusion pour se combiner avec la poudre fondue par un processus de chauffage par arc sous flux en poudre ou laitier électro-conducteur, afin de donner au placage de superalliage la composition du matériau en superalliage souhaité. La couche de poudre comprend une couche de matériau (22) de flux en poudre sur une couche de métal (20) en poudre ou bien les poudres de flux et de métal peuvent être mélangées ensemble (36).
