Abstract
PURPOSE: To reduce erosion, by applying an explosion pressure welding method to clad an erosion-resisting material on the surface of keyway-made portions of a rotor shaft and a wheel which is fitted thereon.
CONSTITUTION: In a steam turbine rotor, a wheel 2 is fitted on a rotor shaft 1 and a key 5 is inserted into keyways 4 made in the shaft 1 and the wheel 2. The wheel 2 is thus secured on the shaft 1. A conjoined material 8 such as austenitic stainless steel, which excels in corrosion resistance and notch sensitivity and whose erosion resistance is higher than that of the material of the shaft 1 and the wheel 2, is previously cladded on at least the keyway-made portions of the shaft 1 and the wheel 2 by an explosion pressure welding method. The keyways 4 are made in the conjoined material 8 cladded. The rotor shaft 1 and the wheel 2 excellent in erosion resistance are thus provided.
