Abstract
The invention relates to an airfoil (1) of a turbine blade. At least one sensor element (2) is integrated into the material of the turbine blade airfoil (1) in order to directly determine the progress of erosion of the turbine blade airfoil (1). The invention further relates to a turbine blade, in particular a turbine blade for the final stage of a turbine, comprising multiple turbine blade airfoils (1) designed in said manner. A device for comparing the progress of erosion of the at least two turbine blade airfoils (1) is provided. The invention finally relates to various methods for directly determining the progress of erosion of an airfoil (1) of a turbine blade.
