Abstract
PURPOSE:To improve the wear resistance and sealing property of a rotor and reduce its cost, by providing an annular recess on the peripheral sliding contact part of the rotor except on both its ends and melting and spraying a wear-resistant material such as ceramic to provide a coating layer in the recess. CONSTITUTION:When the sliding contact portion 14 of a main material 18 which is to be the body of a rotor 13 is shotblasted, a recess 15 is provided on the sliding contact portion 14 except on both its ends 14a, 14a. A wear-resistant material 16 such as ceramic is then molten and sprayed into the recess 15 to make a coating film 17. After that, treatment such as the polishing of the surface of the film 17 is effected. The rotor 13 is thus formed. Since the sliding contact portion 14 is coated with the material 16, the wear resistance of the rotor 13 is improved. Since the material 16 is molten and sprayed into the recess 15 provided away from both the ends 14a, 14a, the chipping of the ends of the rotor 13, the undesired displacement of the molten material 16, etc. are avoided. Because the main material 18 is left at both the ends 14a, 14a, the sealing property of the rotor 13 is also improved.
