PROBLEM TO BE SOLVED: To provide a method of manufacturing a blade 24 assembled on a steam turbine rotor wheel 42. SOLUTION: This method comprises a step for forming a plurality of pockets 30, 32 in an aerofoil part 28 and a step for filling up the pockets with one or more filling materials 40, 38 selected according to a necessary temperature performance. The plurality of pockets comprise radial outside pockets 32 and radial inside pockets 30. The temperature performance of the filling material 38 in the radial outside pockets 32 is higher than that of the filling material 40 in the radial inside pockets 30. COPYRIGHT: (C)2006,JPO&NCIPI |
