Abstract

Die Erfindung betrifft eine Leit- oder Laufschaufeleinrichtung (1), die aus einer Metalllegierung gegossen ist und zumindest eine Schaufelplattform (3) sowie ein einteilig mit der Schaufelplattform (3) ausgebildetes Schaufelblatt (4) umfasst, wobei sich ausgehend von der Schaufelplattform (3) bis zur Spitze des Schaufelblattes (4) ein Hohlraum (6) erstreckt, der durch zumindest eine im Bereich des Schaufelblattes (4) angeordnete und sich zwischen zwei gegenüberliegenden Außenwandungen des Schaufelblattes (4) erstreckende Trennwand (7, 8) in Kammern (9, 10, 11) unterteilt ist, dadurch gekennzeichnet, dass im Bereich der freien Stirnseite der Trennwand (7), die benachbart zur Schaufelplattform (3) angeordnet ist, zumindest ein Vorsprung (13, 14) ausgebildet ist, der in Richtung der Schaufelplattform (3) vorsteht. Ferner betrifft die Erfindung die Verwendung zumindest eines Gießkerns (2) zur Herstellung des Hohlraums (6) einer solchen Leitschaufeleinrichtung (1).
