Abstract

Le procédé consiste à former sur la surface d'une pièce 7 une couche d'un matériau à point de fusion relativement bas, à déplacer l'un par rapport à l'autre un générateur de faisceau laser 10, situé à une certaine distance de la surface de la pièce, et la surface de la pièce en suivant un motif voulu, et à modifier les propriétés chimiques du matériau à bas point de fusion en l'irradiant avec le faisceau laser 11 pour modifier sa couleur.
