FIELD: machine building.
SUBSTANCE: turbine blade for steam turbine consists of section of blade body containing fibrous composite material at least in separate areas and of section of root. Areas of the turbine blade containing fibrous composite material are surrounded with plastic protective layer preventing penetration of moisture into fibrous composite material during turbine blade operation. To control functions of the protective layer an electro-conducting layer or water-soluble chemical substances are installed between the protective layer and fibrous composite material. Another invention of the group refers to the steam turbine containing the above said turbine blade.
EFFECT: increased reliability of steam turbine.
