METHOD FOR MANUFACTURING HIGH-TEMPERATURE LOAD EQUIPMENT FOR JOINTING CARBON MATERIAL AND COPPER ALLOY MATERIAL METALLURGICALLY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing high-temperature load equipment by jointing a carbon material and copper alloy metallurgically, especially a manufacturing method which makes it possible to joint well a CFC block and a cooling tube made of copper alloy in a divertor of a nuclear fusion reactor.

SOLUTION: The high-temperature load equipment is manufactured through the vacuum brazing and aging treatment of assemblies combined by forming a metal layer 12 which can be jointed easily to carbon on the surface of the CFC block 11, a carbon material, laying out the metal layer 12 and a copper alloy material 13 with the intervention of a buffer 15 between them so as to face each other and inserting brazing filler metals 14 and 16 shaped like thin films between the CFC block 11 and the buffer 15 and between it and the copper alloy material 13.
