PURPOSE: To produce a stock having various excellent functions at a lower cost by realizing the formation of a material having a gradient compsn. by a simpler thermal spraying method and forming coating having a gradient compsn. thereon. CONSTITUTION: For forming coating having a gradient compsn., plural powders are individually or mixedly fed to thermal spraying flame and are collided with the material to be thermal sprayed rotating at a high speed, and by the difference in the density in the fused soln. or by the difference in the density of the solidifying temps., the difference in the operation of centrifugal force is utilized, and the coating having a gradient compsn. is formed. |
