Method of manufacturing high-heat-load equipment by metallurgically joining carbon material with copper-alloy material

摘要

A method of manufacturing high-heat-load equipment including a carbon material (11) and a copper alloy material (16) which are joined with each other includes: forming a titanium thin layer (12) on a surface of the carbon material (11); positioning the carbon material so that the titanium thin layer (12) is opposed to the copper alloy material (16) while an interlayer (14) is Interposed between the carbon material (11) and the copper alloy material (16); inserting a brazing material sheet (13,15) into a space between the carbon material (11) and the interlayer (14), as well as into a space between the interlayer (14) and the copper alloy material (16), so as to prepare an assembly of the materials; and subjecting the assembly to a vacuum brazing process and further to an aging process.
