Title:
MANUFACTURING METHOD OF COOLING PASSAGE STRUCTURE, MANUFACTURING METHOD OF NOZZLE HAVING COOLING PASSAGE, AND NOZZLE HAVING COOLING PASSAGE
Document Type and Number:
Japanese Patent JP2004245115
Kind Code:
A
Abstract:
To provide a manufacturing method of a nozzle capable of sufficiently performing diffusion and joining between surfaces of an outer cylinder 11 and an inner cylinder 12 and easily securing a place for mounting a structure.
Diffusion and joining is performed by super-plastically deforming the outer cylinder 11 and the inner cylinder 12 between an outer face cylinder 14 and am inner face cylinder 15 to form a cooling passage 23, oxidation/nitriding by furnace atmosphere is suppressed, the diffusion and joining between the surfaces of the outer cylinder 11 and the inner cylinder 12 is sufficiently performed, and the place for mounting the structure is easily secured by putting the surface into a flat state.
