PURPOSE:To make it possible to improve the corrosion resistance and wear resistance in the material quality characteristics of a rotor by stacking a predetermined number of disk members formed by ceramic material to manufacture the rotor. CONSTITUTION:A rotor shaft 4 is inserted through shaft holes 2 of divided members 1 made from alumina ceramic material, and the positions of vane grooves 3 of the divided members 1 are made coincident with each other in connecting state. Then, keys 5 are inserted between the divided members 1, key grooves 2A and 4A of the rotor shaft 4, and respective divided members 1 and the rotor shaft 4 are fixed by use of a corrosion resisting adhesive or deposition to form the rotor 7. Thus, the corrosion resistance and wear resistance of the rotor are improved. |
