Abstract

The invention discloses a method for manufacturing a W / Cu / CuCrZr composite component. The method comprises the four steps of workpiece treatment, assembling, sealing and welding and hot isostatic pressure treatment. In the workpiece treatment step, a W / Cu composite component and a CuCrZr component used in cooperation with the W / Cu composite component are cleaned up, and then the face, to be in contact, of the W / Cu composite component and / or the face, to be in contact, of the CuCrZr component used in cooperation with the W / Cu composite component are / is plated with a metal layer of 0-0.2 mm. In the hot isostatic pressure treatment step, hot isostatic pressure treatment is carried out on the sealed, welded and assembled W / Cu / CuCrZr composite component. The process has the advantages that operation is easy, tool equipment can be utilized repeatedly, and cost is low, and the obtained W / Cu / CuCrZr composite component has the high interface bonding strength.

Description

technical field [0001] The invention belongs to the field of composite materials for high temperature resistance, corrosion resistance and radiation protection, and particularly relates to a preparation method of a W / Cu / CuCrZr composite component. The composite component is mainly used for furnace body, nuclear, radiation shielding and other materials, especially It is used as a material for nuclear fusion reactors facing plasma. Background technique [0002] The plasma temperature in the nuclear fusion reactor is as high as hundreds of millions of degrees, the ion velocity is high, and the scouring force is strong. Therefore, the plasma-facing materials in the fusion reactor must have the characteristics of high temperature resistance, scouring resistance, and good thermal conductivity. Conventional materials are difficult to meet the requirements of the nuclear fusion reactor. Requirements. At present, ITER (International Thermonuclear Fusion Reactor) adopts W / Cu / CuCrZr t...
