Abstract

Die Erfindung betrifft eine Turbinenschaufel (1), insbesondere eine Endstufenschaufel für eine Dampfturbine, wobei die Turbinenschaufel (1) zumindest bereichsweise aus Faserverbundwerkstoff besteht und die Turbinenschaufel (1) zumindest ein Erosionsschutzbauteil (2) umfasst. Das Erosionsschutzbauteil (2) ist mittels einer formschlüssigen und einer stoffschlüssigen Verbindung an der Turbinenschaufel (1) befestigt. Dies ermöglicht einen sehr sicheren Halt des Erosionsschutzbauteils (2) an der Turbinenschaufel (1) auch bei hohen Umfangsgeschwindigkeiten der Turbinenschaufel (1). Des Weiteren betrifft die Erfindung Verfahren zum Herstellen solchen Turbinenschaufeln (1).
