Abstract: An application jig is used when an erosion shield member is applied to a rotor blade member. The application jig includes a body section disposed on a back side of the rotor blade member; a first pressing section provided in the body section and pressing an erosion shield member to be placed at a leading edge of the rotor blade member from the back side; a second pressing section supported by the body section and pressing a trailing edge of the rotor blade member from the back side; and a third pressing section supported by the body section. The third pressing section is disposed to bypass the trailing edge from the back side to a belly side thereof, is pivotable around a pivot shaft provided in the body section, and presses a portion between the leading and trailing edges in a pivoting direction from the belly side.

Abstract: (1) A nickel-base alloy product having, on the surface thereof, an oxide film comprising at least two layers, namely a first layer mainly composed of Cr2O3 and having a chromium content of not less than 50% relative to the total amount of metal elements and a second layer occurring outside the first layer and mainly composed of MnCr2O4, wherein the grain size of Cr2O3 crystals in the first layer is 50 to 1,000 nm and the total oxide film thickness is 180 to 1,500 nm.
