(FR) PROCÉDÉ DE RÉALISATION D'UNE PIÈCE EN ACIER INOXYDABLE RÉSISTANT À L'USURE ET À LA CORROSION POUR RÉACTEUR NUCLÉAIRE, PIÈCE ET GRAPPE DE COMMANDE CORRESPONDANTES
Abstract: front page image
(EN)This process comprises steps of: - providing a stainless steel preform, - shaping the preform, - finishing the preform in order to form the stainless steel part (21, 27), the finishing step making it possible to prevent the appearance of or to eliminate work hardening at the outer surface (29, 31) of the part (21, 27), - hardening of the outer surface (29, 31) of the part (21, 27) by diffusion of atomic species.
(FR)Ce procédé comprend des étapes de : - fourniture d'une ébauche en acier inoxydable, - façonnage de l'ébauche, - finition de l'ébauche pour former la pièce (21, 27) en acier inoxydable, l'étape de finition permettant d'éviter l'apparition ou d'éliminer un écrouissage à la surface extérieure (29, 31) de la pièce (21, 27), - durcissement de la surface extérieure (29, 31) de la pièce (21, 27) par diffusion d'espèce(s) atomique(s).
