Zusammenfassung:A method for producing a blade for a turbomachine, the blade having a blade tip cladding on its blade tip and an erosion-resistant layer at least on its blade airfoil, wherein firstly a blade tip cladding is applied on the blade tip, subsequently a poorly adhering sublayer is deposited on the blade tip cladding, and then the erosion-resistant layer is produced on the poorly adhering sublayer and the blade airfoil, the poorly adhering sublayer being removed again together with the erosion-resistant layer following completion of the erosion-resistant layer. The invention also relates to a blade for a turbomachine, the blade having a blade tip cladding on its blade tip and an erosion-resistant layer at least on its blade airfoil. The blade tip cladding comprises a metal matrix with incorporated hard material particles and an oxide layer arranged on the metal matrix.
