Abstract

The invention discloses a preparation method of a diamond/W-Cu composite. The preparation method of the diamond/W-Cu composite comprises the steps that W is plated on surfaces of diamond particles through a salt bath plating method first, Cu-clad W composite powder is obtained through a chemical plating method, a certain quantity of W-plated diamond particles and a certain quantity of Cu-clad W composite powder are mixed and press-molded, and an obtained blank is placed in a tube furnace so as to be sintered under the protection of H2, so that the diamond/W-Cu composite is obtained. Accordingto the preparation method of the diamond/W-Cu composite, W-plated diamond is added into the W-Cu composite, so that the heat transmission performance of the W-Cu composite is improved by means of theheat conductivity of the diamond; and meanwhile, W powder is plated with Cu through the chemical plating method so that Cu can be evenly distributed on the surface of the W powder, nonuniform mixing of the W powder and Cu powder is avoided, the compactness of the composite is improved, and the comprehensive performance of the composite is improved.

Description

technical field [0001] The invention relates to a method for preparing a diamond / W-Cu composite material, belonging to the field of metal matrix composite material preparation. Background technique [0002] With the development of social economy and science and technology, energy and environmental issues have become increasingly prominent. Nuclear fusion energy has the advantages of cleanness, safety, and abundant fuel, and has become one of the new energy sources that has attracted much attention. In the ITER device for the development of nuclear fusion energy, the plasma-facing materials need to withstand the high heat generated by the plasma discharge and the thermal action of high particle flux and neutron load, and the excessive heat load will cause the plasma-facing High temperature failure of the material. Therefore, it is necessary to select a heat sink material to transfer heat in a timely and efficient manner, so as to ensure the normal operation of the reactor as...
