<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing turbine components, more specifically, to provide a method of manufacturing a turbine rotor by a cold spraying process. <P>SOLUTION: The method of manufacturing a rotor 10 includes steps for: (a) providing a core shaft 12; (b) cold spraying alloy powder particles onto the core shaft; (c) controlling the cold spraying to form sections 14, 16, 18 at least of different shape along the core shaft to thereby form a near-net shape rotor; and (d) heat treating the near-net shape rotor to relieve stresses and to form diffusion bonding across interfaces between individual powder particles and the core shaft, and finish-shaping the near-net shape rotor. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
