Turbine blade with erosion shield plate

摘要

Disclosed is a turbine blade including a turbine blade substrate (63) including an iron-base alloy; an erosion shield plate (61) including a Co-base alloy; and a shim (62) including a Ni-Fe alloy, in which the erosion shield plate (61) is fixed to a leading edge of the turbine blade substrate (63) with the shim (62) therebetween by an electron beam welding. Thus, a turbine blade having a highly reliable, bonded portion of an erosion shield, and a turbine rotor and a steam turbine using the turbine blade are provided.
