摘要： A coated layer of this invention is composed of a lower alloy-coated layer 2 formed of an MCrAlY alloy whose principal element is Co or Co and Ni, an upper alloy-coated layer 1 formed of an MCrAlY alloy whose principal element is Ni and a portion 4 in which an Al content of the surface portion of the upper coated layer 1 is largest and is reduced gradually towards a more internal part. Manufacturing thereof involves the steps of forming the lower and upper coated layers and effecting an Al diffusion treatment into the upper coated layer. The upper coated layer having the portion which exhibits the large Al content contributes to a high-temperature anticorrosive property. A gas turbine blade is provided with the alloy-coated layer, wherein the lower coated layer incorporates a composite function to prevent a high-temperature corrosion of a base material when cracks are caused in the upper coated layer due to thermal stress. The gas turbine blade exhibits effects of improving the reliability and increasing a life-time.

摘要： Provided are a seal structure and a control method therefor that can improve sealing performance between a rotating portion and a fixed portion, smoothly start up a steam turbine, and suppress the temperature rise of the rotating portion even if the rotating portion is continuously rotated for a long period of time.A seal structure is configured such that seal fins 62 on a seal base-plate 61 side and corresponding breathable spacers 4b on a rotor 2a side are opposed to each other and breathable spacers 4a on the seal base-plate 61 side and corresponding seal fins 2a1 on the rotor 2a side are opposed to each other. The seal base-plate 61 is installed shiftably in a direction coming close to or moving away from the rotor 2a. If steam St has low pressure, the seal fins 62 and the corresponding breathable spacers 4b are not in contact with each other and the seal fins 2a1 and the corresponding breathable spacers 4a are not in contact with each other. If the steam St has high pressure, the seal fins 62 and the corresponding breathable spacers 4b are in contact with each other and the seal fins 2a1 and the corresponding breathable spacers 4a are in contact with each other.
