Embodiment Construction

[0009] In one embodiment, the present invention discloses a method for preparing a statistical composite material, the method comprising the following steps:

[0010] S100, putting the mixed powder into a ball mill tank and adding a ball mill medium for ball milling;

[0011] S200, putting the mixed powder after ball milling into a graphite mold, and then placing them together in a vacuum hot-press furnace for sintering;

[0012] S300. After the sintering is completed, the pressure is released, and the furnace is cooled to room temperature, and the prepared material is a copper-based composite material.

[0013] The method described in this embodiment is simple, and the prepared copper-based composite material has excellent wear resistance and easy processing performance, and is suitable for making components in an environment subject to impact and easy to wear.

[0014] In one embodiment, the mixed powder composition in the step S100 is copper powder and zirconium carbide po...

Abstract

The invention relates to a method for preparing a copper-based composite material. The method uses copper powder and zirconium carbide powder as raw materials, adopts a ball mill to perform ball milling on the raw materials, and the ball milling medium is zirconium carbide balls. Pure argon and sealed. After ball milling, put the mixed powder into a graphite mold and sinter in a vacuum hot-press furnace, keeping constant temperature and applying pressure at the highest sintering temperature. After sintering, the pressure is released, and the furnace is cooled to room temperature, and the prepared material is the copper-based composite material of the present invention. The method of the invention is simple, and the prepared copper-based composite material has excellent wear resistance and easy processing performance, and is suitable for making parts in working conditions subject to impact and easy to wear.

Description

technical field [0001] The invention relates to the field of material synthesis and preparation, in particular to a method for preparing a copper-based composite material. technical background [0002] Copper materials have good electrical conductivity, thermal conductivity and easy processing properties, and are widely used in components such as bearings, bushes, gears, joints and friction. However, due to the low strength and poor wear resistance of pure copper materials, the service life is short and the scope of use is limited. In some specific fields, it is necessary to improve the mechanical properties and mechanical properties of pure copper materials while retaining the metallic properties. [0003] Zirconium carbide is a high-hardness material with metallic properties, and its electrical conductivity can reach 2.3×10 4 S / cm, the electrical conductivity is equivalent to that of metals, and it has a good application prospect in improving the mechanical properties of...
