Abstract: front page image
(EN)The turbine component according to an embodiment comprises a base material configured from an Fe-based alloy containing at least one element selected from the group consisting of Cr, Si, and Al. The base material has, from the interior of the base material toward the surface: a base material section; a composition section which is formed on the surface of the base material section, and which contains a crystal composition comprising crystal grain sizes of the Fe-based alloy that are smaller than the crystal grain sizes of the Fe-based alloy in the base material section; and a carburizing-resistant protective film section which is formed on the surface of the composition section, and which contains at least one element selected from the group consisting of Cr, Si, and Al.
(FR)Le composant de turbine selon un mode de réalisation comprend un matériau de base constitué d'un alliage à base de Fe contenant au moins un élément choisi dans le groupe constitué par Cr, Si et Al. Le matériau de base présente, de l'intérieur du matériau de base vers la surface : une section de matériau de base; une section de composition qui est formée sur la surface de la section de matériau de base, et qui contient une composition cristalline comprenant des tailles de grains cristallins de l'alliage à base de Fe qui sont plus petites que les tailles de grains cristallins de l'alliage à base de Fe dans la section de matériau de base; et une section de film protecteur résistant à la carburation qui est formée sur la surface de la section de composition, et qui contient au moins un élément choisi dans le groupe constitué de Cr, Si et Al.
(JA)実施の形態のタービン部品は、Cr、Si、およびAlからなる群より選ばれる少なくとも1つの元素を含むFe基合金から構成される基材からなる。そして、前記基材は、前記基材の内部から表面に向かって、基材部と、前記基材部の表面に形成され、前記基材部における前記Fe基合金の結晶粒径よりも小さい前記Fe基合金の結晶粒径からなる結晶組織を含む組織部と、前記組織部の表面に形成され、Cr、Si、およびAlからなる群より選ばれる少なくとも1つの元素を含む耐浸炭性保護皮膜部とを有する。
