Abstract

Es ist eine thermische Turbomaschine mit mindestens einer Reihe von Laufschaufeln (1) offenbart. Mindestens eine erste Laufschaufel (1) weist eine grössere radiale Länge als die anderen auf und ist an der Schaufeispitze (2) mit einer ersten abrasiven Schichten (72) ausgestattet. Mindestens eine Laufschaufel (1), welche eine kleinere radiale Länge als die erste Laufschaufel (1) aufweist, ist an der Schaufelspee (2) mit einer zweiten abrasiven Schichten (71) ausgestattet. Die erste abrasive Schichten (72) weist eine bessere Schneidfähigkeit und eine geringere thermische Stabiltät auf, als die zweite abrasive Schicht (71). Die erste abrasive Schicht (72) ist während der Iribetriebnahme der thermischen Turbomaschine mit der abbreibaren Schicht des Stators (8) in Kontakt und die zweite abrasive Schicht (71) ist während des kontinuierlichen Betriebs der thermischen Tu rbomaschine mit der abbreibaren Schicht des Stators (8) in Kontakt.
