Beschreibung
Zusammenfassung:	At least one turbine component for a gas turbine includes a base component formed by casting and an article. The base component includes a platform. The article on the upper surface of the platform is formed by additive manufacturing. The article has a proximal face sized and shaped to cover at least a portion of the upper surface of the platform of the turbine component and a contoured distal face opposite the proximal face. The contoured distal face has a contour surface serving as at least a portion of a hot gas path surface of the turbine component. The contour surface is arranged and disposed to provide a controlled flow pattern of a working fluid across the contour surface based on a mounting location of the turbine component in a turbine. Methods of manufacturing articles and turbine components are also disclosed. L'invention concerne au moins un composant de turbine pour une turbine à gaz comprenant un composant de base formé par coulage et un article. Le composant de base comprend une plateforme. L'article sur la surface supérieure de la plateforme est formé par fabrication additive. L'article a une face proximale dimensionnée et façonnée pour recouvrir au moins une partie de la surface supérieure de la plateforme du composant de turbine et une face distale profilée opposée à la face proximale. La face distale profilée a une surface de forme servant d'au moins une partie d'une surface de trajet de gaz chaud du composant de turbine. La surface de forme est agencée et disposée de façon à fournir un modèle d'écoulement contrôlé d'un fluide de travail à travers la surface de forme sur la base d'un emplacement de montage du composant de turbine dans une turbine. L'invention concerne également des procédés de fabrication d'articles et de composants de turbine.
