Title (EN) METHOD FOR PRODUCING COBALT-BASE ALLOY MEMBER
(FR) PROCÉDÉ POUR LA PRODUCTION D'ÉLÉMENT EN ALLIAGE À BASE DE COBALT
(JA) コバルト基合金部材の製造方法
Abstract:
(EN) Provided is a cobalt-base alloy member having improved oxidation resistance at high temperature. This method for producing a cobalt-base alloy member includes a step for preparing a cobalt-base alloy on which an aluminizing treatment has been performed, and a step for performing, at a degree of vacuum of 1×10-5-1×10-3 Pa, a heat treatment on the cobalt-base alloy on which the aluminizing treatment has been performed.
(FR) L'invention concerne un élément en alliage à base de cobalt ayant une résistance améliorée à l'oxydation à haute température. Le procédé pour la production de cet élément en alliage à base de cobalt comprend une étape consistant à préparer un alliage à base de cobalt sur lequel un traitement d'aluminisation a été effectué et une étape consistant à effectuer, à un degré de vide de 1×10-5 à 1×10-3 Pa, un traitement thermique sur l'alliage à base de cobalt sur lequel le traitement d'aluminisation a été effectué.
(JA) 高温における耐酸化性が向上されたコバルト基合金部材を提供する。コバルト基合金部材の製造方法は、アルミナイジング処理が行われたコバルト基合金を準備する工程と、前記アルミナイジング処理が行われたコバルト基合金に対して、1×10-5Pa~1×10-3Paの真空度で熱処理を行う工程と、を有する。
