A METHOD FOR MODIFYING A WORKPIECE SURFACE USING A HIGH HEAT FLUX PROCESS

A method for forming a workpiece coating having desired coating characteristics is provided. The method employs infrared (IR) radiation to melt the coating while maintaining a lower workpiece core temperature. As a result, the method precludes undesirable microstructural modification of the underlyi...

Zusammenfassung:	A method for forming a workpiece coating having desired coating characteristics is provided. The method employs infrared (IR) radiation to melt the coating while maintaining a lower workpiece core temperature. As a result, the method precludes undesirable microstructural modification of the underlying workpiece. The desired characteristics of the coating are produced by controlling the intensity of, and the time of exposure to, the IR radiation. La présente invention concerne un procédé permettant de réaliser un revêtement de pièce présentant des caractéristiques de revêtement attendues. Le procédé met en oeuvre un rayonnement infrarouge (IR) permettant de faire fondre le revêtement tout en conservant une température inférieure au niveau du coeur de la pièce. Le procédé évite ainsi les modifications microstructurelles indésirables affectant la pièce d'usinage sous-jacente. Pour atteindre les caractéristiques attendues du revêtement, on agit sur l'intensité du rayonnement infrarouge, et sur la durée d'exposition.
