TLDR
In this article, a turbine blade of a steam turbine is characterized as having a highly elastic elastomeric coating on the upper blade side and/or in the turbine blade.
Abstract
The invention relates to a turbine blade (1) of rotor blading or guide blading of a turbine stage, in particular of a turbine output stage, of a steam turbine, wherein at least sections of the turbine blade (1) are composed of metal or fiber composite material, wherein at least in sections a highly elastic elastomeric coating (3) is arranged on the upper blade side and/or in the turbine blade (1), and at least in sections a metal coat (4) is provided on the upper blade surface, in particular on the highly elastic elastomeric coating (4), wherein the metal coat (4) is a thin, energy-absorbing metal coating. The invention further relates to rotor blading or guide blading of a turbine stage, in particular the output stage blading, of a steam turbine, which is characterized in that the rotor blading or guide blading comprises a plurality of turbine blades (1) designed in this way.
